There are so many issues with the code above that answering your direct 
question does not make sense IMHO (but surely someone is going to answer it 
and additionaly point out the issues).
So in hope to be bright and suggest you to search Google for an OOP tutorial 
(possibly in Java) - I actually did:
http://www.google.pl/search?q=java+object+oriented+programmin+tutorial

And you know what - nothing really useful! A lot of material covering 
(somewhat like in an encyclopedia) what an object/class/instance 
variable/method is but nothing really _introductory_ that would illustrate  
"live objects communicating with each other to achieve a goal".

Does anybody know of anything like this online?
