Advertisements


Description

The java.util.BitSet.size() method returns the number of bits of space actually in use by this BitSet to represent bit values. The maximum element in the set is the size - 1st element.

Declaration

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

public int size()

Parameters

  • NA

Return Value

This method returns the number of bits currently in this bit set.

Exception

  • NA

Example

The following example shows the usage of java.util.BitSet.size() 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);

      // print the size of the bitsets
      System.out.println("" + bitset1.size());
      System.out.println("" + bitset2.size());
   }
}

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}
64
