Practical Java ME Game Projects with MIDP is or will likely be the first Java games book for the newly updated and now open source Java Micro Edition (ME). And it will be first and possibly only that covers all MIDP versions 1-3.
Experienced game developer and hacker, Carol Hamer, presents in a clear, accessible writing and exposition with complete working examples. Online updates and discussions are available through her well-known blog site.
From a basic game to professional game projects, this book has what you need to be a mobile Java game developer (and player).
