Java Programming Challenges/exams

[Yohan Weerasinghe]

Hi all,

I am seeking some web sites which contains JAVA programming challenges / free exams / exercise, and which gives us marks/ranks when we complete the challenges. I am talking about sites like CodingBat.com , BlackbeltFactory etc and not about tutorial sites or example sites. Please let me know such sites. Please help.

Thanks for the reply. I logged into that CODECHEFF.COM and did the first question. But unfortunatly, it seems like they have some problem. For the following code, they gave me COMPILE ERROR!!

import java.io.*;
import java.util.*;

public class ScanTest
{
    private static Scanner scan;
    
    public static void main(String[]args)
    {
        scan = new Scanner(System.in);
        
        while(scan.hasNextInt())
        {
            int a = scan.nextInt();
            
            if(a==42)
            {
                break;
            }
            else
            {
                System.out.println(a);
            }
        }
    }
}

I think there certain naming convention you should follow for your class name. I think it should be named as Main, am not sure though. The rules should be available on Codechef site.
