Question

I am submitting my code for Euler10 puzzle at Gild.com in Java using its online editor. The code runs perfectly for all test cases on my PC but compilation on Gild fails. I am following all of its coding rules but I think I’m still missing something.
Here’s my code:

class Euler10 {

public static void main(String[] args) throws java.lang.Exception
{
    java.io.BufferedReader br = new java.io.BufferedReader (new java.io.FileReader(args[0]));
    int number = Integer.parseInt(br.readLine());
    boolean[] isPrime = new boolean[number + 1];
    for (int i = 2; i <= number; i++)
        isPrime[i] = true;
    for (int i = 2; i*i <= number; i++)
    {
        if (isPrime[i])
        {
            for (int j = i; i*j <= number; j++)
                isPrime[i*j] = false;
        }
    }
    long primesum = 0;
    for (int i = 2; i < number; i++)
    {
       if (isPrime[i])
          primesum = primesum+i;
    }
    System.out.println(""+primesum+"\n");
}

}

After compiling this code in debug mode, I get the following error:

My program output shown above is same as the test case output even though it gives wrong result.
Also tell me what is a Diff Output in this context.

(I want to submit the code in the online editor only.)

It seems that the problem is that your output is not identical to the expected output. Try replacing your last line System.out.println(""+primesum+"\n"); with (System.out.println(""+primesum);
