Very Impressed
Never programmed in java beyond the Hello World type application and bought this book. This along with one that covers learning the syntax of java and I have written two useful apps that I have on my phone.
I have something pretty complex as my ultimate goal (although text based - not a game) and feel confident this gives me enough to accomplish that goal.
An Honest Effort, but Little Value
I have always been under the impression that when buying a book of technical nature, one is supposed to purchase a piece of an author's hard-earned, over-the-years experience, otherwise it's just paying for a documentation reprint. Such an experience can be conveyed to a reader in at least two major ways: (1.) a very well-organized, thought-through and consistent presentation of fundamental - yet often complex - concepts (e.g., "Head First Java" by Sierra), or (2.) an in-depth, unique perspective on advanced topics not to be found anywhere else (e.g., "Effective Java" by Bloch). Unfortunately, as far as I can tell, this book delivers neither. As an example of the lack of the former: the discussion of J2ME Configurations and Profiles is almost as muddy and inconsequential as the specification site itself. As an example of the lack of the later: the entire Performance Tuning chapter, a subject I would expect to be critical for success with a mobile platform is about 10 pages, entire page -sized screenshots included. Topics such as real-world compatibility of J2ME across different vendors' implementations is almost not mentioned at all. So, what's left? Basically, a few hundred pages of short, introductory chapters on J2ME APIs, reading pretty much just like Sun Developer Network Reference technical articles or implementation-oriented CodeProject pages. Don't get me wrong, the book authors' hard effort is clearly visible, but you can as well google for "J2ME Record Store tutorial", a "J2ME Bluetooth API tutorial" and so on.
Great Book - even for a java novice
I was still fairly new to Java, but noticed that there was a J2ME study group near me.The bokk helped me both with Java knowledge in general as as well as J2ME in particular

Best JME for beginers ..
this book is very easy to read..good technical explanations.,
easy to understand JME model concept..
reallity from beginner to professional..
very sugested..
If you develop mobile applications buy this one, period.
If you need a no-nonsense, down-to-earth, non-philosophical guide for how to write Java applications for mobile/cellular phones, this is the best book you can buy today. It's very concrete, with lots of working examples etc, and leaves out the fluffy stuff that's so typical for computer books nowadays. The book is an especially good starting point if you are into applications (communicating or non-communicating), but the APIs for writing games are also covered. I hadn't programmed in Java before (yet C and Visual Basic for many years), but I had no problems developing mobile applications after reading this book. Being such a concentrated book means it also works as a reference for when you need to look things up. All in all, this book is for real developers and strongly recommended.
