HashSet hashCode() method in Java with Example

// Java code to demonstrate the working of
// hashCode() method in HashSet

import java.util.*;

public class GFG {
    public static void main(String[] args)
    {
        // creating an HashSet
        HashSet<Integer> arr
            = new HashSet<Integer>();

        // using add() to initialize values
        // [1, 2, 3, 4]
        arr.add(1);
        arr.add(2);
        arr.add(3);
        arr.add(4);

        // print HashSet
        System.out.println("HashSet: "
                           + arr);

        // Get the hashCode value
        // using hashCode() value
        System.out.println("HashCode value: "
                           + arr.hashCode());
