Declaration

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

public int hashCode()

Overrides

hashCode in class Object

Parameters

• NA

Return Value

This method returns a hash code value for this Character.

Exception

• NA

Example

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

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 2 Character objects c1, c2
      Character c1, c2;

      // assign values to c1, c2
      c1 = new Character('z');
      c2 = new Character('Z');

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

      // assign hashcodes of c1, c2 to i1, i2
      i1 = c1.hashCode();
      i2 = c2.hashCode();

      String str1 = "Hashcode of " + c1 + " is " + i1;
      String str2 = "Hashcode of " + c2 + " 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 z is 122
Hashcode of Z is 90
