I bought this book about two months ago when my company was starting a J2ME project. I read the first 6 chapters page for page as an introduction and then used the rest of the book as a reference. I now consider myself a proficient J2ME programmer.

I've used the book mostly as a reference and I have found that the way the chapters are laid out makes it very easy to find whatever information I'm looking for. The chapters on Record Stores are particularly useful.

One reviewer said to just read the online docs. CDLC and MIDP are not very difficult technologies to become proficient at but the documentation online will make it much harder on you. If you don't mind wasting hours of time to save [money] on this book thats fine. But if your time is valuable like mine break down and make the investment. This book and the JavaDocs will be all you need to start professional apps in J2ME.

Initially, What I liked regarding your book verses others was the big picture and the logical layout. You started with the basics - what is the history and the standard. Which was very well laid out, enough information to grab the facts. The second area I felt the book was broken into that all others seem to skip is the how to get started. Step by step, What do you need in software, What additions to the J2SE from Sun. What order do they get installed, What other nice stuff is out there to add (POSE, other emulators). This was well worth the cost of the book to me. I have around five or six "J2ME" books. All just assume this is self evident. If you want to spend a month reading all the standards, software notes, and history of the packages, it is. What I liked on your book was here it is - this is the current stuff and the order to load. This would have saved me several installation attempts of troubleshooting to discover another package is needed or the two I have are different versions. Last is the meat - the break down of the classes. What is or is not ported and some nice basic examples.
I like this approach and would consider it as mandatory to get J2ME up quickly and get a team moving on development in this area. If I went to the store and bought J2SE, CDLC, MIDP, and J2ME, Your book should be in the same package - It is the document that brings it together.

This is the best book on j2me till date. It teaches core concepts in an easy to understand manner.Most books are rich in theory but Core j2me is rich in both Code and Theory.After reading this book you will be able to build you own j2me applications.As this is a book about core J2me it doesnt deal with developing enterprise application with j2me( like XML/security)but it provides you with the solid foundation on which you can build up.My advice is to buy this book if you are a new to j2me,learn the fundamentals and coding techniques from this book.then start reading other articles about xml/security to build enterprise application for j2me.Believe me After reading this book it wont take much time to understand other concepts of j2me.This is the must have book!!It explains everything with code examples.Though it would have been good if mr. Muchow have included shopping cart example in this book,which he demonstrates in his lectures.That would have made it a great book in core j2me aswell as j2me for enterprise application.

This is an ideal book - with the right mix of code and explanation. Books with too much theory drown you with diagrams, whereas you want to hit it asap. I liked the explanations, especially with the wealth of code. If one knows Java, then all one needs is to read the code to quickly understand how it works.

I especially liked the first few chapters, which enabled me to create my entire app by hand before moving on to a GUI. Bcos I had tried the toolkit before reading the book - I know it looked very complex. However, after getting stuff to work step by step manually from the book made me understand the process completely, and then I was able to appreciate and use the toolkit easily.

I found so much useful code - like download pics, http connections, etc.

I do hope a second edition focussing on Japanese mobile phones comes out soon.

I don't have a lot of java experience, but the book was easy to understand. The examples were good and the book seems to cover j2me very well.

Whenever I look for Java books, I almost always go with Sun Press. Every book I have ever read in this series has been outstanding, and Core J2ME is no exception. I was very fortunate to have read this book in it's pre-release stage and I was extremely impressed by the books clarity and explainations. The examples are clear and illustrate their points well. For those people just getting into J2ME programming, I would whole-heartedly recommend this book! I will be recommending it to my J2ME students as an excellent foundation to J2ME.

I really like this book. It was a very detailed introduction to me and is still very useful as a reference.

John Muchow explains all the necessary details, such as UI, RMS, timers, HTTP connections and much more. The 700 pages also include a chapter about using midlets on the Palm OS platform - you get a lot for you money.

If you start with J2ME or want to improve your knowledge, this book is a must-have. Good work, John!

I've bought and read several of the first J2ME books. This book has the best code examples and it has critical information on the MIDP for Palm OS. And there were details about programming MIDP for the PalmVII that I would never have found anywhere else.
I was programming on the PalmVII and had hit a huge roadblock but this book put me back on the right path!

With keen interest in J2ME programming, I try to read as many J2ME books as possible.
Core J2ME is an excellent book for getting started with J2ME programming, and it is the most up-to-date J2ME book on the market now.
The author guides you through step by step from how to set up the environment to develop a complete application.
This book covers different aspects of J2ME very well, especially, Chapter 11 RMS and Chapter 14 HTTP connection are very detailed.
Further more, the author gives a bonus chapter on MIDP for the Palm OS 1.0, which is very informative. This is the only book I found that covers PDA so far.

I have started learning J2ME, and it is my first book of J2ME. I am pretty sure that it will be the one of best choices if you choose this book to start learning J2ME. Examples are very nice to easily understand the concept of J2ME.
