Submitted by Nidhi, on May 08, 2022

Problem statement

In this program, we will create a set using the HashSet collection to store the different types of data elements and print the created collection using the foreach loop.

Source Code

The source code to print a HashSet collection using the foreach loop is given below. The given program is compiled and executed successfully.

// Java program to print a HashSet collection 
// using the foreach loop

import java.util.*;

public class Main {
  public static void main(String[] args) {
    HashSet nums = new HashSet();

    nums.add("One");
    nums.add(2);
    nums.add(3.14);
    nums.add(true);

    System.out.println("Set items: ");
    for (Object item: nums)
      System.out.println(" " + item);
  }
}

Output

Set items: 
 2
 3.14
 One
 true

Explanation

In the above program, we imported the "java.util.*" package to use the HashSet collection.Here, we created a public class Main that contains a main() method.

The main() method is the entry point for the program. And, we created a set nums to store different types of data elements using HashSet collection and printed the created collection using the foreach loop.
