Java BigInteger subtract() method

Thesubtract()method of Java BigInteger class is used tosubtracttwo BigInteger values.This method performs subtraction of this BigInteger and the method argument.This method returns a BigInteger whose value is (this - val).

Syntax:

Parameter:

val - Avalue to be subtracted from this BigInteger entered by user.

Returns:

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

Example 1

import java.math.BigInteger;
public class BigIntegerSubtractExample1{
public static void main(String[] args){
// create 3 BigInteger objects
BigInteger big1,big2,big3;
big1= new BigInteger("1222222222"); 
big2= new BigInteger("1000000000");  

// subtract big1 with big2
 big3= big1.subtract(big2);   

String str="Result of subtractoperation is "+big3;
System.out.println(str);   
}
}

Test it Now

Output:

Result of subtractoperation is 222222222

Example 2

import java.math.BigInteger;
public class BigIntegerSubtractExample2{
public static void main(String[] args){
// create 3 BigInteger objects
BigInteger big1,big2,big3;
big1= new BigInteger("-111"); 
big2= new BigInteger("-100");  

// subtract big1 with big2
 big3= big1.subtract(big2);   

String str="Result of subtractoperation is "+big3;
System.out.println(str);   
}
}
