Exception when compiling hello world

Question

Here's my code.
public class h
     public static void main(String[] args)
          System.out.println("hello");
}The code compiles correctly with no errors. When I run it im getting the following error:
Exception in thread "main" java.lang.noClassDefFoundError : h
Has anyone got any idea why i could be getting this error, thanks.

Answer 1

The -d option was not recognised.
I already use netbeans but I didn't bother for such a small program.
I got it to work anyway. I just had to add the current working dir to the classpath like SET CLASSPATH=%CLASSPATH%;.
