TreeSet hashCode() method in Java with Example

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

import java.util.*;

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

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

        // print TreeSet
        System.out.println("TreeSet: "
                           + LHS);

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