BigInteger not() Method in Java

The java.math.BigInteger.not() method is used to find the bitwise-NOT of a BigInteger. This method returns a negative value if and only if this BigInteger is non-negative. The BigInteger.not() method apply bitwise Not operation upon the current bigInteger. Syntax:

public BigInteger not()

Parameters: The method does not take any parameters. Return Value: The method returns the bitwise-NOT value of a BigInteger with which it is used. Examples:

Input: value = 2300
Output: -2301
Explanation:
Binary of 2300 = 100011111100
NOT of 100011111100 in signed 2's complement is 1111011100000011
Decimal value = -2301.

Input: value = 567689 
Output: -567690

Below program illustrate the not() method of BigInteger(): Java

/*
*Program Demonstrate not() method of BigInteger 
*/
import java.math.*;

public class GFG {

    public static void main(String[] args)
    {

        // Creates  BigInteger object
        BigInteger biginteger = new BigInteger("2300");

        // Call not() method to find ~this
        BigInteger finalvalue = biginteger.not();
        String result = "Result of NOT operation on " + 
        biginteger + " is " + finalvalue;

        // Print result
        System.out.println(result);
    }
}
