Java.util.BitSet.andNot() Method

Description

The java.util.BitSet.andNot(BitSet set) method clears all of the bits in this BitSet whose corresponding bit is set in the specified BitSet.

Declaration

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

public void andNot(BitSet set)

Parameters

• set -- the BitSet with which to mask this BitSet.

Return Value

This method does not return a value.

Exception

• NA

Example

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

      // perform andNot operation for the two  bitsets
      bitset1.andNot(bitset2);

      // print the new bitset1
      System.out.println("" + bitset1);

   }
}

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}
{0, 1, 3, 5}
