Java Map hashCode() Method

// Java program to demonstrates hashCode()
// for different objects
import java.io.*;

class Geeks {
    public static void main(String[] args)
    {
        // Create two different object
        Object o1 = new Object();
        Object o2 = new Object();

        System.out.println("HashCode of obj1: "
                           + o1.hashCode());
        System.out.println("HashCode of obj2: "
                           + o2.hashCode());
    }
}

// Java Program to demonstrate 
// combined hash code for the entire map
import java.util.HashMap;

public class Geeks {
    public static void main(String[] args) {
      
        HashMap<Integer, String> hm = new HashMap<>();

        hm.put(1, "Geek1");
        hm.put(2, "Geek2");
        hm.put(3, "Geek3");
       
        System.out.println("HashMap: " + hm);
      
        // Displaying the hashcode of the map
        System.out.println("HashCode of the HashMap: "
                           + hm.hashCode());
    }
