Java Program to implement NOT operation on BigInteger

The BigInteger.not() method returns a BigInteger whose value is (~this). This method returns a negative value if and only if this BigInteger is non-negative.

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("6");
      two = one.not();
      System.out.println("Result (not operation): " +two);
   }
}

Output

Result (not operation): -7

Let us see another example −

Example

 Live Demo

import java.math.*;
public class Demo {
   public static void main(String[] args) {
      BigInteger bi1, bi2, bi3, bi4;
      bi1 = new BigInteger("9");
      bi2 = new BigInteger("-12");
      bi3 = bi1.not();
      bi4 = bi2.not();
      String str1 = "Result of not operation on " + bi1 +" gives " +bi3;
      String str2 = "Result of not operation on " + bi2 +" gives " +bi4;
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Output

Result of not operation on 9 gives -10
Result of not operation on -12 gives 11
