Get Hash Code for Integer in Java

Java 8 Object Oriented Programming Programming

The HashCode for an Integer can be obtained using the hashCode() method in Java. This method does not accept any parameters and it returns a hash code value of the Integer object.

A program that demonstrates the hashCode() method in Java is given as follows:

Example

Live Demo

import java.lang.*;
public class Demo {
   public static void main(String args[]) {
      Integer i = new Integer(60);
      System.out.println("The integer value is: " + i);
      System.out.println("The Hashcode for the above value is: " + i.hashCode());
   }
}

Output

The integer value is: 60
The Hashcode for the above value is: 60

Now let us understand the above program.

The Integer i is defined. Then the Integer value is printed and its HashCode is also printed using the hashCode() method. A code snippet which demonstrates this is as follows:

Integer i = new Integer(60);
System.out.println("The integer value is: " + i);
System.out.println("The Hashcode for the above value is: " + i.hashCode());
