I'mma be laying down some java chapters, teaching you what you need to know. Since I'm studying for my Sun Developer and Programmer certificates, I'm learning some great shit. I'm going to teach you some of what I learn, by sharing some of my notes with you. I am not going to release any of Sun's study software, but I'll teach with the open-source mentality that they support. First thing you need even before I start is some of the terms you need to know. I'm not pushover, so I expect you to know some stuff coming in. For those that don't understand some of the terms I use, refer to this page, as I'll add terms you might not know. Class - A template that describes the kinds of state and behavior of objects of its type support Object - Every time the JVM sees the "new" keyword, it creates an "object" out of that class. This is considered an instance of a class, and this object has its own state, and behaviors based on the class template. State (instance variables) - Every object (instance of a given class) has its own set of instance variables defined in it. These var Behavior (methods) - When you create a class, you also create "methods" for that class. Basically, these methods are the grunt work, or the logic of your class. It is these behaviors that you call on in order to manipulate data and execute algorithms. You'll get more definitions as I see you needing them. For now, familiarize yourself with these.
