BigInteger not() Method in Java (original) (raw)

Last Updated : 4 Dec, 2018

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);
}

}

`

Output:

Result of NOT operation on 2300 is -2301
