What is the output of this code? import java.util.HashSet; class A { public static void main(String[ ] args) { HashSet set = new

kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A //define class as public.

{

public static void main(String[ ] args) //define main method.

{

HashSet set = new HashSet(); //creating hashset object.

set.add("A"); //add alphabet in hashset

set.add("B"); //add alphabet in hashset

set.add("C"); //add alphabet in hashset

System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

}

Output:

Size of HashSet is : 3

Explanation of the program:

In the above program, we define a public class that is "A" and inside the class, we define the main method.

Inside the main method, we create a HashSet class object that is "set".

To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
