Submitted by Nidhi, on May 08, 2022

Problem Solution:

In this program, we will create a set using the HashSet collection to store the name of cities and print the created collection.

Program/Source Code:

The source code to create a HashSet with string items is given below. The given program is compiled and executed successfully.

// Java program to create a HashSet 
// with string items

import java.util.*;

public class Main {
  public static void main(String[] args) {

    HashSet < String > cities = new HashSet();

    cities.add("MUMBAI");
    cities.add("NEW-DELHI");
    cities.add("AGRA");
    cities.add("INDORE");

    System.out.println("Cities are: \n" + cities);
  }
}

Output:

Cities are: 
[MUMBAI, AGRA, NEW-DELHI, INDORE]

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 to store the name of cities using the HashSet collection and printed the created collection.
