Scala Interview Questions and Answers

1) What is Scala?

Scala is a general-purpose programming language. It supports object-oriented, functional and imperative programming approaches. It is a strong static type language. In Scala, everything is an object whether it is a function or a number. It was designed by Martin Odersky in 2004.

Scala Program Example

object MainObject{
def main(args:Array[String]){
print("Hello Scala")
}
}

2) What are the features of Scala?

There are following features in Scala:

Type inference: In Scala, you don't require to mention data type and function return type explicitly.
Singleton object: Scala uses a singleton object, which is essentially class with only one object in the source file.
Immutability: Scala uses immutability concept. Immutable data helps to manage concurrency control which requires managing data.
Lazy computation: In Scala, computation is lazy by default. You can declare a lazy variable by using the lazy keyword. It is used to increase performance.
Case classes and Pattern matching: In Scala, case classes support pattern matching. So, you can write more logical code.
Concurrency control: Scala provides a standard library which includes the actor model. You can write concurrency code by using the actor.
String interpolation: In Scala, string interpolation allows users to embed variable references directly in processed string literals.
Higher order function: In Scala, higher order function allows you to create function composition, lambda function or anonymous function, etc.
Traits: A trait is like an interface with partial implementation. In Scala, the trait is a collection of abstract and non-abstract methods.
Rich set of collection: Scala provides a rich set of collection library. It contains classes and traits to collect data. These collections can be mutable or immutable.

3) What are the Data Types in Scala?

Data types in Scala are much similar to Java regarding their storage, length, except that in Scala there is no concept of primitive data types every type is an object and starts with capital letter. A table of data types is given below.

Data Types in Scala

Data Type	Default Value	Size
Boolean	False	True or false
Byte	0	8 bit signed value (-2⁷ to 2⁷-1)
Short	0	16 bit signed value(-2¹⁵ to 2¹⁵-1)
Char	'\u0000'	16 bit unsigned Unicode character(0 to 2¹⁶-1)
Int	0	32 bit signed value(-2³¹ to 2³¹-1)
Long	0L	64 bit signed value(-2⁶³ to 2⁶³-1)
Float	0.0F	32 bit IEEE 754 single-precision float
Double	0.0D	64 bit IEEE 754 double-precision float
String	Null	A sequence of characters

4) What is pattern matching?

Pattern matching is a feature of Scala. It works same as switch case in other languages. It matches the best case available in the pattern.

Example

object MainObject {
def main(args: Array[String]) {
var a = 1
a match{
case 1 => println("One")
case 2 => println("Two")
case _ => println("No")
}
}
}

5) What is for-comprehension in Scala?

In Scala, for loop is known as for-comprehensions. It can be used to iterate, filter and return an iterated collection. The for-comprehension looks a bit like a for-loop in imperative languages, except that it constructs a list of the results of all iterations.

Example

object MainObject {
def main(args: Array[String]) {
for( a <- 1 to 10 ){
println(a);
}
}
}

For more information: Click here.

6) What is the breakable method in Scala?

In Scala, there is no break statement, but you can do it by using break method and importing Scala.util.control.Breaks._ package. It can break your code.

Example

import scala.util.control.Breaks._ // Importing package
object MainObject {
def main(args: Array[String]) {
breakable { // Breakable method to avoid exception
for(i<-1 to 10 by 2){
if(i==7)
break // Break used here
else
println(i)
}
}
}
}

7) How to declare a function in Scala?

In Scala, functions are first-class values. You can store function value, pass a function as an argument and return function as a value from other function. You can create a function by using the def keyword. You must mention return type of parameters while defining a function and return type of a function is optional. If you don't specify the return type of a function, default return type is Unit.

Scala Function Declaration Syntax

def functionName(parameters : typeofparameters) : returntypeoffunction = {
// statements to be executed
}

For more information: Click here.

8) Why do we use =(equal) operator in Scala function?

You can create a function with or without = (equal) operator. If you use it, the function will return value. If you don't use it, your function will not return anything and will work like the subroutine.

Example

object MainObject {
def main(args: Array[String]) {
var result = functionExample() // Calling function
println(result)
}
def functionExample() = { // Defining a function
var a = 10
a
}
}

For more information: Click here.

9) What is the Function parameter with a default value in Scala?

Scala provides a feature to assign default values to function parameters. It helps in the scenario when you don't pass value during function calls. It uses default values of parameters.

Example

object MainObject {
def main(args: Array[String]) = {
var result1 = functionExample(15,2) // Calling with two values
var result2 = functionExample(15) // Calling with one value
var result3 = functionExample() // Calling without any value
println(result1+"\n"+result2+"\n"+result3)
}
def functionExample(a:Int = 0, b:Int = 0):Int = { // Parameters with default values as 0
a+b
}
}

For more information: Click here.

10) What is a function named parameter in Scala?

In Scala function, you can specify the names of parameters while calling the function. You can pass named parameters in any order and can also pass values only.

Example

object MainObject {
def main(args: Array[String]) = {
var result1 = functionExample(a = 15, b = 2) // Parameters names are passed during call
var result2 = functionExample(b = 15, a = 2) // Parameters order have changed during call
var result3 = functionExample(15,2) // Only values are passed during call
println(result1+"\n"+result2+"\n"+result3)
}
def functionExample(a:Int, b:Int):Int = {
a+b
}
}

11) What is a higher order function in Scala?

Higher order function is a function that either takes a function as an argument or returns a function. In other words, we can say a function which works with function is called a higher-order function.

Example

object MainObject {
def main(args: Array[String]) = {
functionExample(25, multiplyBy2) // Passing a function as parameter
}
def functionExample(a:Int, f:Int=>AnyVal):Unit = {
println(f(a)) // Calling that function
}
def multiplyBy2(a:Int):Int = {
a*2
}
}

For more information: Click here.

12) What is function composition in Scala?

In Scala, functions can be composed from other functions. It is a process of composing in which a function represents the application of two composed functions.

Example

object MainObject {
def main(args: Array[String]) = {
var result = multiplyBy2(add2(10)) // Function composition
println(result)
}
def add2(a:Int):Int = {
a+2
}
def multiplyBy2(a:Int):Int = {
a*2
}
}

For more information: Click here.

13) What is Anonymous (lambda) Function in Scala?

An anonymous function is a function that has no name but works as a function. It is good to create an anonymous function when you don't want to reuse it later. You can create anonymous function either by using ⇒ (rocket) or _ (underscore) wildcard in Scala.

Example

object MainObject {
def main(args: Array[String]) = {
var result1 = (a:Int, b:Int) => a+b // Anonymous function by using => (rocket)
var result2 = (_:Int)+(_:Int) // Anonymous function by using _ (underscore) wild card
println(result1(10,10))
println(result2(10,10))
}
}

14) What is a multiline expression in Scala?

Expressions those are written in multiple lines are called multiline expression. In Scala, be careful while using multiline expressions.

Example

def add1(a:Int, b:Int) = {
a
+b
}

The above program does not evaluate the complete expression and return b here.

15) What is function currying in Scala?

In Scala, the method may have multiple parameter lists. When a method is called with a fewer number of parameter lists, this will yield a function taking the missing parameter lists as its arguments.

Example

object MainObject {
def add(a:Int)(b:Int) = {
a+b
}
def main(args: Array[String]) = {
var result = add(10)(10)
println("10 + 10 = "+result)
var addIt = add(10)_
var result2 = addIt(3)
println("10 + 3 = "+result2)
}
}

For more information: Click here.

16) What is a nexted function in Scala?

In Scala, you can define the function of variable length parameters. It allows you to pass any number of arguments at the time of calling the function.

Example

object MainObject {
def add(a:Int, b:Int, c:Int) = {
def add2(x:Int,y:Int) = {
x+y
}
add2(a,add2(b,c))
}
def main(args: Array[String]) = {
var result = add(10,10,10)
println(result)
}
}

For more information: Click here.

17) What is an object in Scala?

The object is a real-world entity. It contains state and behavior. Laptop, car, cell phone are the real world objects. An object typically has two characteristics:

1) State: data values of an object are known as its state.

2) Behavior: functionality that an object performs is known as its behavior.

The object in Scala is an instance of a class. It is also known as runtime entity.

For more information: Click here.

18) What is a class in Scala?

The class is a template or a blueprint. It is also known as a collection of objects of similar type.

In Scala, a class can contain:

Data member
Member method
Constructor
Block
Nested class
Superclass information, etc.

Example

class Student{
var id:Int = 0; // All fields must be initialized
var name:String = null;
}
object MainObject{
def main(args:Array[String]){
var s = new Student() // Creating an object
println(s.id+" "+s.name);
}
}

For more information: Click here.

19) What is an anonymous object in Scala?

In Scala, you can create an anonymous object. An object which has no reference name is called an anonymous object. It is good to create an anonymous object when you don't want to reuse it further.

Example

class Arithmetic{
def add(a:Int, b:Int){
var add = a+b;
println("sum = "+add);
}
}
object MainObject{
def main(args:Array[String]){
new Arithmetic().add(10,10);
}
}

For more information: Click here.

20) What is a constructor in Scala?

In Scala, the constructor is not a special method. Scala provides primary and any number of auxiliary constructors. It is also known as default constructor.

In Scala, if you don't specify a primary constructor, the compiler creates a default primary constructor. All the statements of the class body treated as part of the constructor.

Scala Primary Constructor Example

class Student(id:Int, name:String){
def showDetails(){
println(id+" "+name);
}
}
object MainObject{
def main(args:Array[String]){
var s = new Student(101,"Rama");
s.showDetails()
}
}

21) What is method overloading in Scala?

Scala provides method overloading feature which allows us to define methods of the same name but having different parameters or data types. It helps to optimize code. You can achieve method overloading either by using different parameter list or different types of parameters.

Example

class Arithmetic{
def add(a:Int, b:Int){
var sum = a+b
println(sum)
}
def add(a:Int, b:Int, c:Int){
var sum = a+b+c
println(sum)
}
}
object MainObject{
def main(args:Array[String]){
var a = new Arithmetic();
a.add(10,10);
a.add(10,10,10);
}
}

For more information: Click here.

22) What is this in Scala?

In Scala, this is a keyword and used to refer a current object. You can call instance variables, methods, constructors by using this keyword.

Example

class ThisExample{
var id:Int = 0
var name: String = ""
def this(id:Int, name:String){
this()
this.id = id
this.name = name
}
def show(){
println(id+" "+name)
}
}
object MainObject{
def main(args:Array[String]){
var t = new ThisExample(101,"Martin")
t.show()
}
}

23) What is Inheritance?

Inheritance is an object-oriented concept which is used to reusability of code. You can achieve inheritance by using extends keyword. To achieve inheritance, a class must extend to other class. A class which is extended called super or parent class. A class which extends class is called derived or base class.

Example

class Employee{
var salary:Float = 10000
}
class Programmer extends Employee{
var bonus:Int = 5000
println("Salary = "+salary)
println("Bonus = "+bonus)
}
object MainObject{
def main(args:Array[String]){
new Programmer()
}
}

24) What is method overriding in Scala?

When a subclass has the same name method as defined in the parent class, it is known as method overriding. When subclass wants to provide a specific implementation for the method defined in the parent class, it overrides a method from the parent class.

In Scala, you must use either override keyword or override annotation to override methods from the parent class.

Example

class Vehicle{
def run(){
println("vehicle is running")
}
}
class Bike extends Vehicle{
override def run(){
println("Bike is running")
}
}
object MainObject{
def main(args:Array[String]){
var b = new Bike()
b.run()
}
}

For more information: Click here.

25) What is final in Scala?

Final keyword in Scala is used to prevent inheritance of super class members into the derived class. You can declare the final variable, method, and class also.

Scala Final Variable Example

class Vehicle{
final val speed:Int = 60
}
class Bike extends Vehicle{
override val speed:Int = 100
def show(){
println(speed)
}
}
object MainObject{
def main(args:Array[String]){
var b = new Bike()
b.show()
}
}

For more information: Click here.

26) What is the final class in Scala?

In Scala, you can create a final class by using the final keyword. A final class can't be inherited. If you make a class final, it can't be extended further.

Scala Final Class Example

final class Vehicle{
def show(){
println("vehicle is running")
}
}
class Bike extends Vehicle{
override def show(){
println("bike is running")
}
}
object MainObject{
def main(args:Array[String]){
var b = new Bike()
b.show()
}
}

For more information: Click here.

27) What is an abstract class in Scala?

A class which is declared with the abstract keyword is known as an abstract class. An abstract class can have abstract methods and non-abstract methods as well. An abstract class is used to achieve abstraction.

Example

abstract class Bike{
def run()
}
class Hero extends Bike{
def run(){
println("running fine...")
}
}
object MainObject{
def main(args: Array[String]){
var h = new Hero()
h.run()
}
}

For more information: Click here.

28) What is Scala Trait?

A trait is like an interface with partial implementation. In Scala, the trait is a collection of abstract and non-abstract methods. You can create a trait that can have all abstract methods or some abstract and some non-abstract methods.

Example

trait Printable{
def print()
}
class A4 extends Printable{
def print(){
println("Hello")
}
}
object MainObject{
def main(args:Array[String]){
var a = new A4()
a.print()
}
}

For more information: Click here.

29) What is a trait mixins in Scala?

In Scala, "trait mixins" means you can extend any number of traits with a class or abstract class. You can extend only traits or combination of traits and class or traits and abstract class.

It is necessary to maintain the order of mixins otherwise compiler throws an error.

Example

trait Print{
def print()
}
abstract class PrintA4{
def printA4()
}
class A6 extends PrintA4 {
def print(){ // Trait print
println("print sheet")
}
def printA4(){ // Abstract class printA4
println("Print A4 Sheet")
}
}
object MainObject{
def main(args:Array[String]){
var a = new A6() with Print // You can also extend trait during object creation
a.print()
a.printA4()
}
}

30) What is the access modifier in Scala?

Access modifier is used to define accessibility of data and our code to the outside world. You can apply accessibly to class, trait, data member, member method, and constructor, etc. Scala provides the least accessibility to access to all. You can apply any access modifier to your code according to your requirement.

In Scala, there are only three types of access modifiers.

No modifier
Protected
Private

31) What is an array in Scala?

In Scala, the array is a combination of mutable values. It is an index based data structure. It starts from 0 index to n-1 where n is the length of the array.

Scala arrays can be generic. It means, you can have an Array[T], where T is a type parameter or abstract type. Scala arrays are compatible with Scala sequences - you can pass an Array[T] where a Seq[T] is required. Scala arrays also support all the sequence operations.

Example

class ArrayExample{
var arr = Array(1,2,3,4,5) // Creating single dimensional array
def show(){
for(a<-arr) // Traversing array elements
println(a)
println("Third Element = "+ arr(2)) // Accessing elements by using index
}
}
object MainObject{
def main(args:Array[String]){
var a = new ArrayExample()
a.show()
}
}

For more information: Click here.

32) What is an ofDim method in Scala?

Scala provides an ofDim method to create a multidimensional array. The multidimensional array is an array which stores data in matrix form. You can create from two dimensional to three, four and many more dimensional array according to your need.

Example

class ArrayExample{
var arr = Array.ofDim[Int](2,2) // Creating multidimensional array
arr(1)(0) = 15 // Assigning value
def show(){
for(i<- 0 to 1){ // Traversing elements by using loop
for(j<- 0 to 1){
print(" "+arr(i)(j))
}
println()
}
println("Third Element = "+ arr(1)(1)) // Accessing elements by using index
}
}
object MainObject{
def main(args:Array[String]){
var a = new ArrayExample()
a.show()
}
}

For more information: Click here.

33) What is String in Scala?

In Scala, the string is a combination of characters, or we can say it is a sequence of characters. It is index-based data structure and uses a linear approach to store data into memory. The string is immutable in Scala like java.

Example

class StringExample{
var s1 = "Scala string example"
def show(){
println(s1)
}
}
object MainObject{
def main(args:Array[String]){
var s = new StringExample()
s.show()
}
}

For more information: Click here.

34) What is string interpolation in Scala?

Starting in Scala 2.10.0, Scala offers a new mechanism to create strings from your data. It is called string interpolation. String interpolation allows users to embed variable references directly in processed string literals. Scala provides three string interpolation methods: s, f and raw.

Example

class StringExample{
var pi = 3.14
def show(){
println(s"value of pi = $pi")
}
}
object MainObject{
def main(args:Array[String]){
var s = new StringExample()
s.show()
}
}

For more information: Click here.

35) What does s method in Scala String interpolation?

The s method of string interpolation allows us to pass a variable in the string object. You don't need to use the + operator to format your output string. This variable is evaluated by the compiler and replaced by value.

Example

class StringExample{
var s1 = "Scala string example"
def show(){
println(s"This is $s1")
}
}
object MainObject{
def main(args:Array[String]){
var s = new StringExample()
s.show()
}
}

For more information: Click here.

36) What does f method in Scala String interpolation?

The f method is used to format your string output. It is like printf function of C language which is used to produce formatted output. You can pass your variables of any type in the print function.

Example

class StringExample{
var s1 = "Scala string example"
var version = 2.12
def show(){
println(f"This is $s1%s, scala version is $version%2.2f")
}
}
object MainObject{
def main(args:Array[String]){
var s = new StringExample()
s.show()
}
}

For more information: Click here.

37) What does raw method in Scala String interpolation?

The raw method of string interpolation is used to produce a raw string. It does not interpret special char present in the string.

Example

class StringExample{
var s1 = "Scala \tstring \nexample"
var s2 = raw"Scala \tstring \nexample"
def show(){
println(s1)
println(s2)
}
}
object MainObject{
def main(args:Array[String]){
var s = new StringExample()
s.show()
}
}

38) What is exception handling in Scala?

Exception handling is a mechanism which is used to handle abnormal conditions. You can also avoid termination of your program unexpectedly.

Scala makes "checked vs. unchecked" very simple. It doesn't have checked exceptions. All exceptions are unchecked in Scala, even SQLException, and IOException.

Example

class ExceptionExample{
def divide(a:Int, b:Int) = {
a/b // Exception occurred here
println("Rest of the code is executing...")
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample()
e.divide(100,0)
}
}

For more information: Click here.

39) What is try catch in Scala?

Scala provides try and catch block to handle the exception. The try block is used to enclose suspect code. The catch block is used to handle exception occurred in the try block. You can have any number of the try-catch block in your program according to need.

Example

In this example, we have two cases in our catch handler. The first case will handle only arithmetic type exception. The second case has a Throwable class which is a super-class in the exception hierarchy. The second case can handle any type of exception in your program. Sometimes when you don't know about the type of exception, you can use super-class.

class ExceptionExample{
def divide(a:Int, b:Int) = {
try{
a/b
var arr = Array(1,2)
arr(10)
}catch{
case e: ArithmeticException => println(e)
case ex: Throwable =>println("found a unknown exception"+ ex)
}
println("Rest of the code is executing...")
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample()
e.divide(100,10)
}
}

For more information: Click here.

40) What is finally in Scala?

The finally block is used to release resources during exception. Resources may be a file, network connection, database connection, etc. The finally block executes guaranteed.

Example

class ExceptionExample{
def divide(a:Int, b:Int) = {
try{
a/b
var arr = Array(1,2)
arr(10)
}catch{
case e: ArithmeticException => println(e)
case ex: Exception =>println(ex)
case th: Throwable=>println("found a unknown exception"+th)
}
finally{
println("Finaly block always executes")
}
println("Rest of the code is executing...")
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample()
e.divide(100,10)
}
}

41) What is throw in Scala?

You can throw an exception explicitly in your code. Scala provides throw keyword to throw an exception. The throw keyword mainly used to throw a custom exception.

Example

class ExceptionExample2{
def validate(age:Int)={
if(age<18)
throw new ArithmeticException("You are not eligible")
else println("You are eligible")
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample2()
e.validate(10)
}
}

For more information: Click here.

42) What is exception propagation in Scala?

In Scala, you can propagate the exception in calling chain. When an exception occurs in any function, it looks for the handler. If handler not available there, it forwards to caller method and looks for handler there. If handler presents there, handler catch that exception. If the handler does not present, it moves to next caller method in calling chain. This whole process is known as exception propagation.

43) What are throws in Scala?

Scala provides throws keyword for declaring the exception. You can declare an exception with method definition. It provides information to the caller function that this method may throw this exception. It helps to caller function to handle and enclose that code in a try-catch block to avoid abnormal termination of the program. In Scala, you can either use throws keyword or throws annotation to declare the exception.

Example

class ExceptionExample4{
@throws(classOf[NumberFormatException])
def validate()={
"abc".toInt
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample4()
try{
e.validate()
}catch{
case ex : NumberFormatException => println("Exception handeled here")
}
println("Rest of the code executing...")
}
}

For more information: Click here.

44) What is a custom exception in Scala?

In Scala, you can create your exception. It is also known as custom exceptions. You must extend Exception class to while declaring custom exception class. You can create your message in custom class.

Example

class InvalidAgeException(s:String) extends Exception(s){}
class ExceptionExample{
@throws(classOf[InvalidAgeException])
def validate(age:Int){
if(age<18){
throw new InvalidAgeException("Not eligible")
}else{
println("You are eligible")
}
}
}
object MainObject{
def main(args:Array[String]){
var e = new ExceptionExample()
try{
e.validate(5)
}catch{
case e : Exception => println("Exception Occured : "+e)
}
}
}

45) What is a collection in Scala?

Scala provides a rich set of collection library. It contains classes and traits to collect data. These collections can be mutable or immutable. You can use them according to your requirement.

For more information: Click here.

46) What is traversable in Scala collection?

It is a trait and used to traverse collection elements. It is a base trait for all Scala collections. It contains the methods which are common to all collections.

For more information: Click here.

47) What does Set in Scala collection?

It is used to store unique elements in the set. It does not maintain any order for storing elements. You can apply various operations on them. It is defined in the Scala.collection.immutable package.

Example

In this example, we have created a set. You can create an empty set also. Let's see how to create a set.

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
val set1 = Set() // An empty set
val games = Set("Cricket","Football","Hocky","Golf") // Creating a set with elements
println(set1)
println(games)
}
}

48) What does SortedSet in Scala collection?

In Scala, SortedSet extends Set trait and provides sorted set elements. It is useful when you want sorted elements in the Set collection. You can sort integer values and string as well.

It is a trait, and you can apply all the methods defined in the traversable trait and Set trait.

Example

import scala.collection.immutable.SortedSet
object MainObject{
def main(args:Array[String]){
var numbers: SortedSet[Int] = SortedSet(5,8,1,2,9,6,4,7,2)
numbers.foreach((element:Int)=> println(element))

49) What is HashSet in Scala collection?

HashSet is a sealed class. It extends AbstractSet and immutable Set trait. It uses hash code to store elements. It neither maintains insertion order nor sorts the elements.

Example

import scala.collection.immutable.HashSet
object MainObject{
def main(args:Array[String]){
var hashset = HashSet(4,2,8,0,6,3,45)
hashset.foreach((element:Int) => println(element+" "))
}
}

50) What is BitSet in Scala?

Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The largest number stored in it determines the memory footprint of a bitset. It extends Set trait.

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var numbers = BitSet(1,5,8,6,9,0)
numbers.foreach((element:Int) => println(element))
}
}

51) What is ListSet in Scala collection?

In Scala, ListSet class implements immutable sets using a list-based data structure. In ListSet class elements are stored internally in a reversed insertion order, which means the newest element is at the head of the list. This collection is suitable only for a small number of elements. It maintains insertion order.

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var listset = ListSet(4,2,8,0,6,3,45)
listset.foreach((element:Int) => println(element+" "))
}
}

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var seq:Seq[Int] = Seq(52,85,1,8,3,2,7)
seq.foreach((element:Int) => print(element+" "))
println("\nAccessing element by using index")
println(seq(2))
}
}

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var vector:Vector[Int] = Vector(5,8,3,6,9,4) //Or
var vector2 = Vector(5,2,6,3)
var vector3 = Vector.empty
println(vector)
println(vector2)
println(vector3)
}
}

54) What is List in Scala Collection?

The List is used to store ordered elements. It extends LinearSeq trait. It is a class for immutable linked lists. This class is useful for last-in-first-out (LIFO), stack-like access patterns. It maintains order, can contain duplicates elements.

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var list = List(1,8,5,6,9,58,23,15,4)
var list2:List[Int] = List(1,8,5,6,9,58,23,15,4)
println(list)
println(list2)
}
}

55) What is the Queue in the Scala Collection?

Queue implements a data structure that allows inserting and retrieving elements in a first-in-first-out (FIFO) manner.

In Scala, Queue is implemented as a pair of lists. One is used to insert the elements and second to contain deleted elements. Elements are added to the first list and removed from the second list.

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var queue = Queue(1,5,6,2,3,9,5,2,5)
var queue2:Queue[Int] = Queue(1,5,6,2,3,9,5,2,5)
println(queue)
println(queue2)
}
}

56) What is a stream in Scala?

The stream is a lazy list. It evaluates elements only when they are required. This is a feature of Scala. Scala supports lazy computation. It increases the performance of your program.

Example

object MainObject{
def main(args:Array[String]){
val stream = 100 #:: 200 #:: 85 #:: Stream.empty
println(stream)
}
}

57) What does Map in Scala Collection?

The map is used to store elements. It stores elements in pairs of key and values. In Scala, you can create a map by using two ways either by using comma separated pairs or by using rocket operator.

Example

object MainObject{
def main(args:Array[String]){
var map = Map(("A","Apple"),("B","Ball"))
var map2 = Map("A"->"Aple","B"->"Ball")
var emptyMap:Map[String,String] = Map.empty[String,String]
println(map)
println(map2)
println("Empty Map: "+emptyMap)
}
}

58) What does ListMap in Scala?

This class implements immutable maps by using a list-based data structure. You can create empty ListMap either by calling its constructor or using ListMap.empty method. It maintains insertion order and returns ListMap. This collection is suitable for small elements.

Example

import scala.collection.immutable._
object MainObject{
def main(args:Array[String]){
var listMap = ListMap("Rice"->"100","Wheat"->"50","Gram"->"500") // Creating listmap with elements
var emptyListMap = new ListMap() // Creating an empty list map
var emptyListMap2 = ListMap.empty // Creating an empty list map
println(listMap)
println(emptyListMap)
println(emptyListMap2)
}
}

59) What is a tuple in Scala?

A tuple is a collection of elements in the ordered form. If there is no element present, it is called an empty tuple. You can use a tuple to store any data. You can store similar type of mixing type data. You can return multiple values by using a tuple in function.

Example

object MainObject{
def main(args:Array[String]){
var tuple = (1,5,8,6,4) // Tuple of integer values
var tuple2 = ("Apple","Banana","Gavava") // Tuple of string values
var tuple3 = (2.5,8.4,10.50) // Tuple of float values
var tuple4 = (1,2.5,"India") // Tuple of mix type values
println(tuple)
println(tuple2)
println(tuple3)
println(tuple4)
}
}

60) What is a singleton object in Scala?

Singleton object is an object which is declared by using object keyword instead by class. No object is required to call methods declared inside a singleton object.

In Scala, there is no static concept. So Scala creates a singleton object to provide an entry point for your program execution.

Example

object Singleton{
def main(args:Array[String]){
SingletonObject.hello() // No need to create object.
}
}
object SingletonObject{
def hello(){
println("Hello, This is Singleton Object")
}
}

61) What is a companion object in Scala?

In Scala, when you have a class with the same name as a singleton object, it is called a companion class and the singleton object is called a companion object. The companion class and its companion object both must be defined in the same source file.

Example

class ComapanionClass{
def hello(){
println("Hello, this is Companion Class.")
}
}
object CompanoinObject{
def main(args:Array[String]){
new ComapanionClass().hello()
println("And this is Companion Object.")
}
}

62) What are case classes in Scala?

Scala case classes are just regular classes which are immutable by default and decomposable through pattern matching. It uses the equal method to compare instance structurally. It does not use the new keyword to instantiate the object.

Example

case class CaseClass(a:Int, b:Int)
object MainObject{
def main(args:Array[String]){
var c = CaseClass(10,10) // Creating object of case class
println("a = "+c.a) // Accessing elements of case class
println("b = "+c.b)
}
}

63) What is file handling in Scala?

File handling is a mechanism for handling file operations. Scala provides predefined methods to deal with the file. You can create, open, write and read the file. Scala provides a complete package scala.io for file handling.

Example

import scala.io.Source
object MainObject{
def main(args:Array[String]){
val filename = "ScalaFile.txt"
val fileSource = Source.fromFile(filename)
for(line<-fileSource.getLines){
println(line)
}
fileSource.close()
}
}

1. What type of people do you not work well with?Be very careful answering this question as most organization employ professionals with an array of personalities and characteristics. You don't want to give the impression that you're going to have problems working with anyone currently employed at the organization.

Only disloyalty to the organization or lawbreaking should be on your list of personal characteristics of people you can't work with.2. How did you hear about the position At LabCorp?Another seemingly innocuous interview question, this is actually a perfect opportunity to stand out and show your passion for and connection to the company and for job At LabCorp. For example, if you found out about the gig through a friend or professional contact, name drop that person, then share why you were so excited about it. If you discovered the company through an event or article, share that. Even if you found the listing through a random job board, share what, specifically, caught your eye about the role.3. Your client is upset with you for a mistake you made, how do you react?Acknowledge their pain - empathize with them. Then apologize and offer a solution to fix the mistake.4.

I believe a positive attitude is the foundation of being successful - it's contagious in the workplace, with our customers, and ultimately it's the difference maker.48. Why should we select you not others?Here you need to give strong reasons to your interviewer to select you not others. Sell yourself to your interviewer in interview in every possible best way. You may say like I think I am really qualified for the position. I am a hard worker and a fast learner, and though I may not have all of the qualifications that you need, I know I can learn the job and do it well.”49. If you were an animal, which one would you want to be?Seemingly random personality-test type questions like these come up in interviews generally because hiring managers want to see how you can think on your feet. There's no wrong answer here, but you'll immediately gain bonus points if your answer helps you share your strengths or personality or connect with the hiring manager. Pro tip: Come up with a stalling tactic to buy yourself some thinking time, such as saying, “Now, that is a great question. I think I would have to say… ”50. What is your biggest regret to date and why?Describe honestly the regretful action / situation you were in but then discuss how you proactively fixed / improved it and how that helped you to improve as a person/worker.51. Describe to me the position At LabCorp you're applying for?This is a “homework” question, too, but it also gives some clues as to the perspective the person brings to the table. The best preparation you can do is to read the job description and repeat it to yourself in your own words so that you can do this smoothly at the interview.52. What was the most important task you ever had?There are two common answers to this question that do little to impress recruiters:☛ ‘I got a 2.1'☛ ‘I passed my driving test'No matter how proud you are of these achievements, they don't say anything exciting about you. When you're going for a graduate job, having a degree is hardly going to make you stand out from the crowd and neither is having a driving licence, which is a requirement of many jobs.53. How would you observe the level of motivation of your subordinates?Choosing the right metrics and comparing productivity of everyone on daily basis is a good answer, doesn't matter in which company you apply for a supervisory role.54. Do you have good computer skills?It is becoming increasingly important for medical assistants to be knowledgeable about computers. If you are a long-time computer user with experience with different software applications, mention it. It is also a good idea to mention any other computer skills you have, such as a high typing rate, website creation, and more.55. Where do you see yourself professionally five years from now At LabCorp?Demonstrate both loyalty and ambition in the answer to this question. After sharing your personal ambition, it may be a good time to ask the interviewer if your ambitions match those of the company.Download Interview PDF 56. Give me an example of an emergency situation that you faced. How did you handle it?There was a time when one of my employers faced the quitting of a manager in another country. I was asked to go fill in for him while they found a replacement and stay to train that person. I would be at least 30 days. I quickly accepted because I knew that my department couldn't function without me.57. How have you changed in the last five years?All in a nutshell. But I think I've attained a level of personal comfort in many ways and although I will change even more in the next 5-6 years I'm content with the past 6 and what has come of them.58. Explain an idea that you have had and have then implemented in practice?Often an interview guide will outline the so-called ‘STAR' approach for answering such questions; Structure the answer as a situation, task, action, and result: what the context was, what you needed to achieve, what you did, and what the outcome was as a result of your actions.59. Why should the we hire you as this position At LabCorp?This is the part where you link your skills, experience, education and your personality to the job itself. This is why you need to be utterly familiar with the job description as well as the company culture. Remember though, it's best to back them up with actual examples of say, how you are a good team player.60. What is your desired salary At LabCorp?Bad Answer: Candidates who are unable to answer the question, or give an answer that is far above market. Shows that they have not done research on the market rate, or have unreasonable expectations.Good answer: A number or range that falls within the market rate and matches their level of mastery of skills required to do the job.61. Why do you want to work At LabCorp for this organisation?Being unfamiliar with the organisation will spoil your chances with 75% of interviewers, according to one survey, so take this chance to show you have done your preparation and know the company inside and out. You will now have the chance to demonstrate that you've done your research, so reply mentioning all the positive things you have found out about the organisation and its sector etc. This means you'll have an enjoyable work environment and stability of employment etc – everything that brings out the best in you.62. Explain me about your experience working in this field At LabCorp?I am dedicated, hardworking and great team player for the common goal of the company I work with. I am fast learner and quickly adopt to fast pace and dynamic area. I am well organized, detail oriented and punctual person.63. What would your first 30, 60, or 90 days look like in this role At LabCorp?Start by explaining what you'd need to do to get ramped up. What information would you need? What parts of the company would you need to familiarize yourself with? What other employees would you want to sit down with? Next, choose a couple of areas where you think you can make meaningful contributions right away. (e.g., “I think a great starter project would be diving into your email marketing campaigns and setting up a tracking system for them.”) Sure, if you get the job, you (or your new employer) might decide there's a better starting place, but having an answer prepared will show the interviewer where you can add immediate impact-and that you're excited to get started.64. What do you think is your greatest weakness?Don't say anything that could eliminate you from consideration for the job. For instance, "I'm slow in adapting to change" is not a wise answer, since change is par for the course in most work environments. Avoid calling attention to any weakness that's one of the critical qualities the hiring manager is looking for. And don't try the old "I'm a workaholic," or "I'm a perfectionist.65. Tell me something about your family background?First, always feel proud while discussing about your family background. Just simple share the details with the things that how they influenced you to work in an airline field.66. Are you planning to continue your studies and training At LabCorp?If asked about plans for continued education, companies typically look for applicants to tie independent goals with the aims of the employer. Interviewers consistently want to see motivation to learn and improve. Continuing education shows such desires, especially when potentials display interests in academia potentially benefiting the company.Answering in terms of “I plan on continuing my studies in the technology field,” when offered a question from a technology firm makes sense. Tailor answers about continued studies specific to desired job fields. Show interest in the industry and a desire to work long-term in said industry. Keep answers short and to the point, avoiding diatribes causing candidates to appear insincere.67. Describe a typical work week for this position At LabCorp?Interviewers expect a candidate for employment to discuss what they do while they are working in detail. Before you answer, consider the position At LabCorp you are applying for and how your current or past positions relate to it. The more you can connect your past experience with the job opening, the more successful you will be at answering the questions.68. What type of work environment do you prefer?Ideally one that's similar to the environment of the company you're applying to. Be specific.69. How would you rate your communication and interpersonal skills for this job At LabCorp?These are important for support workers. But they differ from the communication skills of a CEO or a desktop support technician. Communication must be adapted to the special ways and needs of the clients. Workers must be able to not only understand and help their clients, but must project empathy and be a warm, humane presence in their lives.70. Do you have any questions for me?Good interview questions to ask interviewers at the end of the job interview include questions on the company growth or expansion, questions on personal development and training and questions on company values, staff retention and company achievements.Download Interview PDF 71. How would you motivate your team members to produce the best possible results?Trying to create competitive atmosphere, trying to motivate the team as a whole, organizing team building activities, building good relationships amongst people.72. How do you act when you encounter competition?This question is designed to see if you can rise the occasion. You want to discuss how you are the type to battle competition strongly and then you need to cite an example if possible of your past work experience where you were able to do so.73. What would you like to have accomplished by the end of your career?Think of 3 major achievements that you'd like to accomplish in your job when all is said and done - and think BIG. You want to show you expect to be a major contributor at the company. It could be creating a revolutionary new product, it could be implementing a new effective way of marketing, etc.74. What do you think we could do better or differently?This is a common one at startups. Hiring managers want to know that you not only have some background on the company, but that you're able to think critically about it and come to the table with new ideas. So, come with new ideas! What new features would you love to see? How could the company increase conversions? How could customer service be improved? You don't need to have the company's four-year strategy figured out, but do share your thoughts, and more importantly, show how your interests and expertise would lend themselves to the job.75. What features of your previous jobs have you disliked?It's easy to talk about what you liked about your job in an interview, but you need to be careful when responding to questions about the downsides of your last position. When you're asked at a job interview about what you didn't like about your previous job, try not to be too negative. You don't want the interviewer to think that you'll speak negatively about this job or the company should you eventually decide to move on after they have hired you.76. How would your friends describe you?My friends would probably say that I'm extremely persistent – I've never been afraid to keep going back until I get what I want. When I worked as a program developer, recruiting keynote speakers for a major tech conference, I got one rejection after another – this was just the nature of the job. But I really wanted the big players – so I wouldn't take no for an answer. I kept going back to them every time there was a new company on board, or some new value proposition. Eventually, many of them actually said "yes" – the program turned out to be so great that we doubled our attendees from the year before. A lot of people might have given up after the first rejection, but it's just not in my nature. If I know something is possible, I have to keep trying until I get it.77. Do you think you have enough experience At LabCorp?If you do not have the experience they need, you need to show the employer that you have the skills, qualities and knowledge that will make you equal to people with experience but not necessary the skills. It is also good to add how quick you can pick up the routine of a new job role.
