BigInteger negate() Method in Java

Prerequisite: BigInteger Basics The java.math.BigInteger.negate() method returns a BigInteger whose value is (- this). negate() method will change the signed bit of BigInteger. Syntax:

public BigInteger negate()

Parameters: The method does not accept any parameter. Return Value: The method returns the operation of (- this). Examples:

Input: value = 2300
Output: -2300
Explanation:
Binary signed 2's complement of 2300 = 0000100011111100
Signed bit are 0000
change sign bit to 1111
so negate of 0000100011111100 in signed 2's complement is 1111011100000100
Decimal value = -2300.

Input: value = 567689 
Output: -567689 

Below program illustrates negate() method of BigInteger. 

Java

/*
*Program Demonstrate negate() method of BigInteger
*/
import java.math.*;

public class GFG {

    public static void main(String[] args)
    {

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

        // Call negate() method to find -this
        BigInteger finalvalue = biginteger.negate();
        String result = "Result of negate operation on " +
        biginteger + " is " + finalvalue;

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

Output:

Result of negate operation on 2300 is -2300
