Implement AND-NOT Operation on BigInteger in Java

TheBigInteger.andNot(BigInteger val) returns a BigInteger whose value is (this & ~val). This method, which is equivalent to and(val.not()), is provided as a convenience for masking operations. This method returns a negative BigInteger if and only if this is negative and val is positive. Here, “val” is the value to be complemented and AND'ed with this BigInteger.

The following is an example −

Example

 Live Demo

import java.math.*;
public class Demo {
   public static void main(String[] args) {
      BigInteger one, two, three;
      one = new BigInteger("12");
      two = new BigInteger("6");
      three = one.andNot(two);
      System.out.println("Result (andNot operation): " +three);
   }
}

Output

Result (andNot operation): 8

Let us see another example −

Example

 Live Demo

import java.math.*;
public class Demo {
   public static void main(String[] args) {
      BigInteger bi1, bi2, bi3;
      bi1 = new BigInteger("9");
      bi2 = new BigInteger("2");
      bi3 = bi1.andNot(bi2);
      String str = "Result of andNot operation is " +bi3;;
      System.out.println( str );
   }
}

Output

Result of andNot operation is 9
