BitSet Class and() method

• and() method is available in java.util package.
• and() method is used to perform logical AND between two Bitset. This bit set is updated so that every bit holds the value true when and only when both bitsets holds the value true.
• and() method is a non-static method, so it is accessible with the class object and if we try to access the method with the class name then we will get an error.
• and() method does not throw an exception at the time of operating logical AND.

Syntax:

    public void and(Bitset bs);

Parameter(s):

• BitSet bs – represents a bit set (like an integer number).

Return value:

The return type of this method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void and() method of BitSet.

import java.util.*;

public class AndOfBitSet {
    public static void main(String[] args) {
        // create an object of two BitSet
        BitSet bs1 = new BitSet(10);
        BitSet bs2 = new BitSet(10);

        // By using set() method is to set
        // the values in BitSet 1 
        bs1.set(10);
        bs1.set(20);
        bs1.set(30);
        bs1.set(40);
        bs1.set(50);

        // By using set() method is to set
        // the values in BitSet 2 
        bs2.set(60);
        bs2.set(70);
        bs2.set(50);
        bs2.set(40);
        bs2.set(30);

        // Display Bitset1 and BitSet2
        System.out.println("bs1 :" + bs1);
        System.out.println("bs2:" + bs2);

        // By using and() method is to perform
        // logical AND between two BitSet(i.e. It returns
        // Common values)

        bs1.and(bs2);

        // Display BitSet 1
        System.out.println("bs1.and(bs2) : " + bs1);
    }
}

Output

bs1 :{10, 20, 30, 40, 50}
bs2:{30, 40, 50, 60, 70}
bs1.and(bs2) : {30, 40, 50}
