Implement BigInteger in Java

Question

Java have a special feature called bigInteger which can be used when we need to use a integer which can't be adjust in long. below is an example of how to use bigInteger in java. in the example code i used 10 and 5 as the value of bigInteger but u can assign any integer value i repeat any integer value in place of it. there are no limitation in it like we have in int or long.

import java.math.BigInteger;
import java.util.Scanner;

public class BigIntegerEx {

public static void main(String[] args) {

BigInteger a, b, c, sum, subtract, multiply, divide, abs, max, min;
a = new BigInteger("10"); //declearing a bigInteger which value is 10
b = new BigInteger("5"); //declearing another bigInteger which value is 10

sum = a.add(b); //add a and b
subtract = a.subtract(b); //subtract b form a
multiply = a.multiply(b); //multiply a by b
divide = a.divide(b); //divide a by b
abs = (b.subtract(a)).abs(); //find the absolute value of (b-a)
max = a.max(b); //find the maximum of a and b
min = a.min(b); //find the minimum of a and b

System.out.println("Sum = "+ sum + ", Subtract = "+ subtract + ", Multiply = "+ multiply + ", Divide = "+ divide + ", ABS = "+ abs + ", MAX = " + max + ", MIN = "+ min); //printing all the value we got

Scanner sc = new Scanner(System.in); //create a scanner object to scan a biginteger value.
c = sc.nextBigInteger(); //scan a bigInteger value
System.out.println("Scaned value: " + c); //print the scanned bigInteger value
}

}

Answer 1

Niloy, I guess this isn't a question right?

Answer 2

of course not. haha...
