Java BitSet | XOR

Java BitSet | XOR

Last Updated : 31 Jul, 2021

BitSet is a class defined in the java.util package. It creates an array of bits represented by boolean values.

Syntax

public void xor(BitSet set);

Explanation:
The method performs a logical XOR, such that in the BitSet, a bit is set if and only if the bit initially has the value true, and the corresponding bit in the argument has the value false, and vice-versa.

Examples:

Input : 
set1 : {1, 2, 4}
set2 : {2, 3, 4}

Output :
After performing st1.xor(set2)
set2 : {1, 3}

Program:

Java

// Java program illustrating Bitset Class Function.
import java.util.*;
public class GFG {
    public static void main(String[] args)
    {
        // Constructors of BitSet class
        BitSet bs1 = new BitSet();
        BitSet bs2 = new BitSet(6);

        /* set is BitSet class method
        explained in next articles */
        bs1.set(0);
        bs1.set(1);
        bs1.set(2);
        bs1.set(4);

        // assign values to bs2
        bs2.set(4);
        bs2.set(6);
        bs2.set(5);
        bs2.set(1);
        bs2.set(2);
        bs2.set(3);

        // Printing the 2 Bitsets
        System.out.println("bs1 : " + bs1);
        System.out.println("bs2 : " + bs2);

        // Performing logical AND
        // on bs2 set with bs1
        bs2.xor(bs1);

        // bs2 set after Performing AND
        System.out.println("After Performing XOR :");
        System.out.println(bs2);
    }
}

Output:

bs1 : {0, 1, 2, 4}
bs2 : {1, 2, 3, 4, 5, 6}
After Performing XOR :
{0, 3, 5, 6}
