AAH! I compiled my "Hello Wrold" app, and ran it, and it threw this error:

Exception in thread "main" java.lang.NoClassDefFoundError: HELLOWROLD/java

Here's my code:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, world!");
    }
}

Is there anything I'm doing wrong? Or is my Terminal just being an idiot?
