BitSet class methods in Java

The BitSet class creates a special type of array that holds bit values. The BitSet array can increase in size as needed.

Following are the methods of the BitSet class −

Let us now see an example wherein we are working on BitSet AND(), OR(), & XOR() methods −

Example

import java.util.BitSet;
public class BitSetDemo {
   public static void main(String args[]) {
      BitSet bits1 = new BitSet(16);
      BitSet bits2 = new BitSet(16);
      // set some bits
      for(int i = 0; i < 16; i++) {
         if((i % 2) == 0) bits1.set(i);
         if((i % 5) != 0) bits2.set(i);
      }
      System.out.println("Initial pattern in bits1: ");
      System.out.println(bits1);
      System.out.println("
Initial pattern in bits2: ");
      System.out.println(bits2);
      // AND bits
      bits2.and(bits1);
      System.out.println("
bits2 AND bits1: ");
      System.out.println(bits2);
      // OR bits
      bits2.or(bits1);
      System.out.println("
bits2 OR bits1: ");
      System.out.println(bits2);
      // XOR bits
      bits2.xor(bits1);
      System.out.println("
bits2 XOR bits1: ");
      System.out.println(bits2);
   }
}

Output

Initial pattern in bits1:
{0, 2, 4, 6, 8, 10, 12, 14}
Initial pattern in bits2:
{1, 2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14}
bits2 AND bits1:
{2, 4, 6, 8, 12, 14}
bits2 OR bits1:
{0, 2, 4, 6, 8, 10, 12, 14}
bits2 XOR bits1:
{}
