Not sure if this kind of help is accepted to ask for here, tell me if it isn't.

It has to get done before tomorrow, it's not entirerly finished but it should work somewhat ok by now. I'm trying to use the Eclipse debugger (not very used to it).

I have my top-level or main class, which is Game, in which I have a constructor and a main method. In the main method I create a new "Game", initiating the constructor.

    public static void main(String[] args){
    Game chess = new Game();
}

public Game(){
    Board board = new Board();

That's the first thing the debugger reacts to:

Thread [main] (Suspended)   
ClassNotFoundException(Object).<init>() line: 20 [local variables unavailable]  
ClassNotFoundException(Throwable).<init>(String, Throwable) line: 217   
ClassNotFoundException(Exception).<init>(String, Throwable) line: not available 
ClassNotFoundException.<init>(String) line: not available   
URLClassLoader$1.run() line: not available  
AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method]   
Launcher$ExtClassLoader(URLClassLoader).findClass(String) line: not available   
Launcher$ExtClassLoader.findClass(String) line: not available   
Launcher$ExtClassLoader(ClassLoader).loadClass(String, boolean) line: not available 
Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: not available 
Launcher$AppClassLoader.loadClass(String, boolean) line: not available  
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available  
Game.<init>() line: 15  
Game.main(String[]) line: 11

Line 11 is the one line in my main method, line 15 is the instantiation of "board".
