Example

In the following code shows how to use BitSet.size() method.

//from w  ww  .j a  v  a  2s .  co  m


import java.util.*;

public class Main {

   public static void main(String[] args) {

      
      BitSet bitset1 = new BitSet(8);
      BitSet bitset2 = new BitSet(8);

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

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

      // 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());
   }
}

The code above generates the following result.
