Unable to comile my class file

[vishalku]

Hello,
I am new to this site and
I am trying to submit solution of "universe" problem but i am getting compile error each time i am submitting the solution.
Here is my code:

public class Main {

public static void main (String[] args) throws java.lang.Exception
  {
     BufferedReader r = new BufferedReader (new InputStreamReader (System.in));
     String s;
     while (!(s=r.readLine()).startsWith("42")) System.out.println(s);
  }

}

please tell me where i am going wrong.

If you click where it says "Compile Error" it will tell you what error the compiler is giving.

[mk12345]

you didn't import anything import java.io.BufferedReader;
import java.io.InputStreamReader; and compile again.

[mk12345]

what is the difference between int and INTEGER.
