This topic offers a gallery of straight-shooting Java applications that illustrate how to use the concepts we've covered in complete, working, real-world type applications. After all, that is the purpose of all this ”to get us writing complete applications. The idea is that you will really understand how the concepts fit together if you see them fitting together. It can be very frustrating to read a book filled with tiny code snippets, none of which compile on their own, so I didn't want to do that. Here, therefore, is a collection of different small applications that you can study, incorporate into your own projects, or otherwise use freely as you see fit. Although I don't warrant the usability of this code for any particular purpose, it is presented here in order to support the topics of this book, to help you learn to program Java better. Translation: Use it, sell it, do whatever you want with it; I wouldn't launch my space shuttle on it though, and I wouldn't wonder ( aloud , to me, in e-mail) why certain "features" are "missing," because its purpose is academic. Though it would generally be fine in production. Some concepts are presented in a simplified, or repeated manner, in order to help the ideas sink in. Comments interspersed frequently throughout the files provide the discussion. This will hopefully encourage you to use code comments to communicate with the inheritors of your applications, instead of relying on model documents or using case diagrams. |
