Java.lang.Byte.hashCode() Method

---

Description

The java.lang.Byte.hashCode() returns a hash code for this Byte which is equal to the result of invoking intValue().

Declaration

Following is the declaration for java.lang.Byte.hashCode() method

public int hashCode()

Overrides

hashCode in class Object

Parameters

NA

Return Value

This method returns a hash code value for this Byte.

Exception

NA

Example

The following example shows the usage of lang.Byte.hashCode() method.

package com.tutorialspoint;

import java.lang.*;

public class ByteDemo {

   public static void main(String[] args) {

      // create 2 Byte objects b1, b2
      Byte b1, b2;

      // create 2 int i1, i2
      int i1, i2;

      // assign values to b1, b2
      b1 = new Byte("100");
      b2 = new Byte("-100");

      // assign hash code of b1, b2 to i1, i2
      i1 = b1.hashCode();
      i2 = b2.hashCode();

      String str1 = "Hashcode of Byte " + b1 + " is " + i1;
      String str2 = "Hashcode of Byte " + b2 + " is " + i2;

      // print i1, i2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result −

Hashcode of Byte 100 is 100
Hashcode of Byte -100 is -100
