Thread: Exercise

I'm running the following code in my editor for the following exercise: Sphere Online Judge (SPOJ) - Problem ADUN
Seems to run fine in my editor though I am being judged as giving the wrong answer, where am I going wrong?

import java.io.*;
import java.math.BigInteger;
import java.util.Scanner;
 
 class AddingTwoNumbers{
 
 
	public static void main(String[] args)throws Exception{
		try{
		Scanner scanner = new Scanner(System.in);
		Scanner scanner2 = new Scanner(System.in);
		BigInteger count = scanner.nextBigInteger();
		BigInteger count1 = scanner2.nextBigInteger();
		System.out.println(addingNumbers(count,count1));
 
		}catch(Exception e){
			return;
		}
		}
 
	public static BigInteger addingNumbers(BigInteger firstLine, BigInteger secondLine){
		return firstLine.add(secondLine);
	}
}

As in the example when code is given input 10 and 20, ouput is 30. So seems good plus I've tried the code with much larger numbers and works though keep getting errors like NZEC/ wrong answer/ compilation. It's my first time using spoj so getting frustrated.

That's the trouble there is no wrong output in my editor, spoj is basically a challenge site which evaluates my code based on problems.
Thanks anyway, I've decided to give up spoj.
