---

---

Description

The Java BitSet xor(BitSet set) method performs a logical XOR of this bit set with the bit set argument.

Declaration

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

public void xor(BitSet set)

Parameters

set − a bit set.

Return Value

This method does not return a value.

Exception

NA

Performing XOR opearation on BitSets Example

The following example shows the usage of Java BitSet xor() method. We're creating two BitSets. We're setting true values at given indexes to the BitSet objects using set() method calls per index and using xor() method we're performing xor opearation and print the updated bitset.

package com.tutorialspoint;

import java.util.BitSet;

public class BitSetDemo {
   public static void main(String[] args) {

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

      // assign values to bitset1
      bitset1.set(0, 6, true);

      // 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 xor operation between two bitsets
      bitset1.xor(bitset2);

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

Output

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, 6, 8, 10}

Performing XOR opearation on BitSets of Bytes Example

The following example shows the usage of Java BitSet xor() method. We're creating two BitSets using byte[] and using or() method we're performing xor opearation and print the updated bitset.

package com.tutorialspoint;

import java.util.BitSet;

public class BitSetDemo {
   public static void main(String[] args) {

      // create 2 bitsets
      BitSet bitset1 = BitSet.valueOf(new byte[] { 0, 1, 2, 3, 4, 5 });
      BitSet bitset2 = BitSet.valueOf(new byte[] { 2, 4, 6, 8, 10 });

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

      // perform xor operation between two bitsets
      bitset1.xor(bitset2);

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

Output

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

Bitset1:{8, 17, 24, 25, 34, 40, 42}
Bitset2:{1, 10, 17, 18, 27, 33, 35}
{1, 8, 10, 18, 24, 25, 27, 33, 34, 35, 40, 42}

Performing XOR opearation on BitSets of Longs Example

The following example shows the usage of Java BitSet xor() method. We're creating two BitSets using long[] and using xor() method we're performing xor opearation and print the updated bitset.

package com.tutorialspoint;

import java.util.BitSet;

public class BitSetDemo {
   public static void main(String[] args) {

      // create 2 bitsets
      BitSet bitset1 = BitSet.valueOf(new long[] { 0, 1, 2, 3, 4, 5 });
      BitSet bitset2 = BitSet.valueOf(new long[] { 2, 4, 6, 8, 10 });

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

      // perform xor operation between two bitsets
      bitset1.xor(bitset2);

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

Output

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

Bitset1:{64, 129, 192, 193, 258, 320, 322}
Bitset2:{1, 66, 129, 130, 195, 257, 259}
{1, 64, 66, 130, 192, 193, 195, 257, 258, 259, 320, 322}
