BigInteger negate() Method in Java

• Last Updated : 04 Dec, 2018

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.

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
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        System.out.println(result);    }}
Output:
Result of negate operation on 2300 is -2300
