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

Constructors:

/ \

BitSet() BitSet(int no_Of_Bits)

BitSet() : A no-argument constructor to create an empty BitSet object.

BitSet(int no_Of_Bits) : A one-constructor with an integer argument to create an instance of the BitSet class with an

initial size of the integer argument representing the number of bits.*/

//Example 1

package bitset;

import java.util.BitSet;

public class bitset1 {

public static void main(String args[])

{

Bitset bits1=new BitSet(16);

BitSet bits2=new BitSet(16);

for(int i=0;i<16;i++){

if((i%2)==0) bits1.set(i);

if((i%5)!=0) bits2.set(i);

}

System.out.println("initial pattern in bits1");

System.out.println(bits1);

System.out.println("initial pattern in bits2");

System.out.println(bits2);

bits2.and(bits1);

System.out.println("\n bits2 AND bits1");

System.out.println(bits2);

bits2.or(bits1);

System.out.println("\n bits2 OR bits1");

System.out.println(bits2);

bits2.xor(bits1);

System.out.println("\n bits2 XOR bits1");

System.out.println(bits2);

}}

Output:

initial Pattern in bits1

{0,2,4,6,8,10,12}

initial Pattern in bits2

{1,2,3,4,5,6,7,8,9,11,12,13,14}

bits2 AND bits1:

{2,4,6,8,12,14}

bits 2 or bits1:

{0,2,4,6,8,10,12,14}

bits XOR bits1:

{}

//Example 2

package bitset;

import java.util.*;

public class bcons {

public static void main(String args[])

{

BitSet bs1=new BitSet();

BitSet bs2=new BitSet(6);

bs1.set(0);

bs1.set(1);

bs1.set(2);

bs1.set(4);

bs2.set(4);

bs2.set(6);

bs2.set(5);

bs2.set(1);

bs2.set(2);

bs2.set(3);

System.out.println("bs1"+bs1);

System.out.println("bs2"+bs2);

}}

Output: bs1{0,1,2,4}

bs2{1,2,3,4,5,6}
