Read the problem statement. It's only one sentence.

Java has a built-in BigInteger class. A sample Java solution for this problem is as follows:

[code]import java.util.Scanner;
import java.math.BigInteger;

public class aplusb2 {
    public static void main(String[] foo) {
        Scanner in = new Scanner(System.in);
        System.out.println((new BigInteger(in.next())).add(new BigInteger(in.next())));
    }
}[/code]

import java.util.Scanner; 
import java.math.BigInteger; 
 
public class aplusb2 { 
    public static void main(String[] foo) { 
        Scanner in = new Scanner(System.in); 
        System.out.println((new BigInteger(in.next())).add(new BigInteger(in.next()))); 
    } 
}

What's the difference between
public static void main(String[] args)
and
public static void main(String[] foo)?

If that's a sample Java solution for this problem, then why can't we submit it in JAVA? I mean, if you say that that is a way to solve it, then it means that there is a way to solve it in JAVA

64 bit integers cannot hold numbers of 100000 digits (i.e., of size 10^100000)

yes, otherwise the problem would be trivial.

Integers only have a capacity of -2[sup]31[/sup] to 2[sup]31[/sup] -1 which is 10 digits long while this problem has input that may be up to 100 000 digits each. So you'll have to find another method to solve this. For future reference don't post your code in the comments and please refer to this before posting a question.

It's exactly as the problem states: add two numbers together, each of which may be up to 100 000 digits long.

Note that python is disallowed because it has bignums.
