Java.util.BitSet.hashcode() Method

Description

The java.util.BitSet.hashcode() method returns a hash code value for this bit set. The hash code depends only on which bits have been set within this BitSet.

Declaration

Following is the declaration for java.util.BitSet.hashcode() method

public int hashCode()

Parameters

• NA

Return Value

This method returns a hash code value for this bit set.

Exception

• NA

Example

The following example shows the usage of java.util.BitSet.hashCode() method.

package com.tutorialspoint;

import java.util.*;

public class BitSetDemo {

   public static void main(String[] args) {

      // create 2 bitsets
      BitSet bitset1 = new BitSet(8);
      BitSet bitset2 = new BitSet(8);

      // assign values to bitset1
      bitset1.set(0);
      bitset1.set(1);
      bitset1.set(2);
      bitset1.set(3);
      bitset1.set(4);
      bitset1.set(5);

      // assign values to bitset2
      bitset2.set(2);
      bitset2.set(4);
      bitset2.set(6);
      bitset2.set(8);
      bitset2.set(10);

      // print the sets
      System.out.println("Bitset1:" + bitset1);
      System.out.println("Bitset2:" + bitset2);

      // return a hashcode for each bitset
      System.out.println("" + bitset1.hashCode());
      System.out.println("" + bitset2.hashCode());

   }
}

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

Bitset1:{0, 1, 2, 3, 4, 5}
Bitset2:{2, 4, 6, 8, 10}
