public final class BitSetCardinality {
	public static void main(String[] args) {

		BitSet obj = new BitSet(8);
		BitSet obj1 = new BitSet(8);

		obj.set(0);
		obj.set(1);
		obj.set(2);
		obj.set(3);

		obj1.set(2);
		obj1.set(4);

		obj1.set(8);

		System.out.println("The Value in obj:" + obj);
		System.out.println("The Value in obj1" + obj1);

		System.out.println("" + obj.cardinality());
		System.out.println("" + obj1.cardinality());
