Hello all I need help with java. On Tuesday we will be having a test on superclasses and subclasses. There will be basic questions such as: Can a subclass inherit from a superclass's private instance variables? The answer is no. However, I really need to work on the free response section my teacher will be giving. It is called a "design question." Can anyone give any advice as to what the best way is for studying for the free response? Has anyone ever heard of a "design question?" Also, what are the best Java books out on the market (heard Deitel and Deitel is pretty good) Any advice is greatly appreciated. Thanks!
