Syntax:

Returns:

This method returns a BigInteger whose value is (-this).

Parameter:

Exception:

Example 1

import java.math.BigInteger;
public class BigIntegerNegateExample1{
public static void main(String[] args){
// create 2 BigInteger objects
BigInteger big1,big2;
big1= new BigInteger("1000"); 
// assign negate value of big1 to big2
big2= big1.negate();   
String str="Negated value of  "+  big1+" is "+big2;
System.out.println(str);   
}
}

Test it Now

Output:

Negated value of 1000 is -1000

Example 2

import java.math.BigInteger;
public class BigIntegerNegateExample2{
public static void main(String[] args){
// create 2 BigInteger objects
BigInteger big1,big2;
big1= new BigInteger("-123"); 
// assign negate value of big1 to big2
big2= big1.negate();   
String str="Negated value of  "+  big1+" is "+big2;
System.out.println(str);   
}
}
