How to perform logical AND operation on BitSet in Java ?

Declaration :

public void and(BitSet set)

1	public void and(BitSet set)

Explanation :

Purpose	The and(BitSet set) method 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.
Parameters	set ===> a bit set
Return Value	This method does not return a value.
Exception	NA

Java Program : Example

Below example will explain java.util.BitSet.and() method.

package com.c4learn;
import java.util.*;
public class BitSetExample {
   public static void main(String[] args) {
      // creating two bitsets
      BitSet bitsetObj1 = new BitSet(8);
      BitSet bitsetObj2 = new BitSet(8);
      // Assign values to bitsetObj1
      bitsetObj1.set(10);
      bitsetObj1.set(11);
      bitsetObj1.set(12);
      bitsetObj1.set(13);
      bitsetObj1.set(14);
      bitsetObj1.set(15);
      // Assign values to bitsetObj2
      bitsetObj2.set(12);
      bitsetObj2.set(14);
      bitsetObj2.set(16);
      bitsetObj2.set(18);
      bitsetObj2.set(10);
      // Print the bitset
      System.out.println("Value of Bitset Obj 1 : " + bitsetObj1);
      System.out.println("Value of Bitset Obj 2 : " + bitsetObj2);
      // and operation
      bitsetObj1.and(bitsetObj2);
      // Print the bitsetObj1
      System.out.println("and operation result : " + bitsetObj1);
   }
}

package com.c4learn;

import java.util.*;

public class BitSetExample {

public static void main(String[] args) {

// creating two bitsets

BitSet bitsetObj1 = new BitSet(8);

BitSet bitsetObj2 = new BitSet(8);

// Assign values to bitsetObj1

bitsetObj1.set(10);

bitsetObj1.set(11);

bitsetObj1.set(12);

bitsetObj1.set(13);

bitsetObj1.set(14);

bitsetObj1.set(15);

// Assign values to bitsetObj2

bitsetObj2.set(12);

bitsetObj2.set(14);

bitsetObj2.set(16);

bitsetObj2.set(18);

bitsetObj2.set(10);

// Print the bitset

System.out.println("Value of Bitset Obj 1 : " + bitsetObj1);

System.out.println("Value of Bitset Obj 2 : " + bitsetObj2);

// and operation

bitsetObj1.and(bitsetObj2);

// Print the bitsetObj1

System.out.println("and operation result : " + bitsetObj1);

}

Output of Program :

Value of Bitset Obj 1 : {10, 11, 12, 13, 14, 15}
Value of Bitset Obj 2 : {10, 12, 14, 16, 18}
and operation result : {10, 12, 14}

Value of Bitset Obj 1 : {10, 11, 12, 13, 14, 15}

Value of Bitset Obj 2 : {10, 12, 14, 16, 18}

and operation result : {10, 12, 14}
