"Graphic Java: Mastering the JFC: Volume 1: AWT" is readable, understandable (with the prerequisite understanding of basic Java). It's the best so far that I've seen, and I'm buying the next volume in the series. However, it could be improved. The diagramming language is Booch, rather than today's standard UML. Some chapters seem poorly organized at a coarse level. There are a few mistakes here and there, such as: * Use of 'l' (lowercase L) as a variable name. This is generally-recognized-as-unreadable. It took me some time to realize it wasn't a one. * On p. 321, a use in code of "implements" for a class, rather than "extends", and in English, a use of "extends" where "implements" is intended ("cannot _extend_ an adapter class"). * a suggestion that inner classes "provide a mechanism similar to callbacks (function pointers) in C." It would better be stated that _interfaces_ can provide a mechanism similar to function pointers, and one use of inner classes, iff they implement an interface accepted as a callback, is to _define_ the callback.
