Java BitSet - xor() Method

The java.util.BitSet.xor() method is used to perform a logical XOR operation on the given BitSet with the specified BitSet argument. The given BitSet is modified so that a bit in it has the value true if one of the following statements holds:

• The bit initially has the value true, and the corresponding bit in the argument has the value false.
• The bit initially has the value false, and the corresponding bit in the argument has the value true.

Syntax

public void xor(BitSet set)

Parameters

Return Value

void type.

Exception

NA.

Example:

In the example below, the java.util.BitSet.xor() method is used to perform XOR operation on a given BitSet called BSet1 using the specified BitSet called BSet2.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating two BitSet
    BitSet BSet1 = new BitSet();
    BitSet BSet2 = new BitSet();

    //populating BSet1
    BSet1.set(2);
    BSet1.set(4);
    BSet1.set(6);
    BSet1.set(8);
    BSet1.set(10);

    //populating BSet2
    BSet2.set(4);
    BSet2.set(8);
    BSet2.set(12);   

    //printing BSet1
    System.out.println("Before XOR, BSet1 contains: " + BSet1);

    //performing XOR operation on 
    //BSet1 using BSet2
    BSet1.xor(BSet2);

    //printing BSet1
    System.out.println("After XOR, BSet1 contains: " + BSet1);
  }
}

The output of the above code will be:

Before XOR, BSet1 contains: {2, 4, 6, 8, 10}
After XOR, BSet1 contains: {2, 6, 10, 12}
