Answer 1

import java.util.*; 

public class MyClass {
    public static void main(String args[]) {
        BitSet bs1 = new BitSet();
        BitSet bs2 = new BitSet(); 
        
        bs1.set(1); 
        bs1.set(2); 
        bs1.set(3);         
        
        bs2.set(1); 
        bs2.set(5); 
        bs2.set(3); 

        System.out.println(bs1); 
        System.out.println(bs2); 
        
        bs1.andNot(bs2);

        System.out.println(bs1); 
    }
}
