Geek Week

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


public BigInteger negate()

Parameters: The method does not accept any parameter.

Return Value: The method returns the operation of (- this).


Input: value = 2300
Output: -2300
Binary signed 2's complement of 2300 = 0000100011111100
Singed bit are 0000
change sing 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.

*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
Result of negate operation on 2300 is -2300
