Java BitSet | and

Prerequisite : Java BitSet | Set 1

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

Performs a logical AND of this target bit set with the argument bit set. This bit set is modified so that each bit in it has the value true if and only if it both initially had the value true and the corresponding bit in the bit set argument also had the value true.


public void and(BitSet set);


Input : 
set1 : {1, 2, 4}
set2 : {2, 3, 4}
Output : After performing st1.and(set2)
set2 : {2, 4}






// Java program illustrating Bitset Class constructors.
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
        expalined in next articles */
        // assign values to bs2
        // Printing the 2 Bitsets
        System.out.println("bs1 : " + bs1);
        System.out.println("bs2 : " + bs2);
        // Performing logical AND
        // on bs2 set with bs1
        // bs2 set after Performing AND
        System.out.println("\nAfter AND operation : ");



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

After AND operation : 
{1, 2, 4}
