Two Java Programming Guides

Here are two Java Programming Guides, written by C. J. Whyley, from the Department of Computer Science, University of Wales Swansea. These will help you become a better Java programming, or get started programming in Java. The first one, from their Programming in Java course, is a 20-page document explaining the basic Java programming topics, such as Objects, Classes, Methods, Variable, Debugging, Collections, Libraries, Inheritance. The second one listed below reviews and teaches building a graphical user interface, programming with exceptions, concurrent programming with threads, and design patterns.

Programming in Java Course Notes  
Programs written in Java - an Object-Oriented language - consist of several objects communicating with each other in order to solve a task. Each object has properties and behaviour. Details of an object's properties are contained in its fields, and its behaviour is defined in it methods. An object is described by a class. A class can have several different objects. It is easiest to think of a class as being a sort of factory, which is responsible for making objects. (20 pages, 208kb, pdf format)
