Product Description

<p>Although Java is incredibly popular, the standard edition of Java is way too big and bulky to build applications for wireless devices such as PDAs and phones. Thus, Sun has released Java 2 Platform, Micro Edition (J2ME). J2ME has the potential to be as revolutionary in the wireless space as Java has been in the server space.</p>

<p><i>Wireless Java: Developing with J2ME, Second Edition</i> is updated to include coverage of the next version of programs for mobile Java devices. MIDP 2.0 contains many exciting new features, such as sound HTTPS support, lots of user interface API enhancements, a Game API, and much more. Also, author Jonathan Knudsen makes clear what material is new so readers can still use the book for MIDP 1.0/CLDC 1.0.</p>

About the Author

Jonathan began his object-oriented programming career in Objective-C on the NeXT OS, soon thereafter suffering through a couple of purgatorial years in Microsoft’s Visual C++, before graduating to Java in 1996. He has written extensively about Java and LEGO robots, including five books, a monthly online column called "Bite-Size Java," and articles for JavaWorld, EXE, NZZ Folio, and the O'Reilly Network. Jonathan holds a degree in mechanical engineering from Princeton University.

5.0 out of 5 stars Get up and running really fast., March 21, 2003

By	Mark Spritzler (Long Beach, CA USA) - See all my reviews (REAL NAME)

I just got the pleasure of finishing this book. After just two days of reading I wrote my first MIDLet. Using a Servlet and a MIDLet I created an app that runs on a cell phone. I mean how cool is that.

And Jonathan's writing style makes it very easy to understand and to read. No rereading over pages because you couldn't understand what you just read.

If you are a Java programmer, as that is one requirement, that you know how to program in Java already, and you want to write apps for PDAs and Cell Phones, then this is the book to buy.

5.0 out of 5 stars Superb, just excellent, January 31, 2002

By	Frederic Daoud (Montreal, Canada) - See all my reviews

This review is from: Wireless Java : Developing with Java 2, Micro Edition (Paperback)

This book is excellent. I wish many more books were like this one. I cannot express how much I enjoyed this book. There are just too many books out there that are just flashy, bulky, in-your-face, and just bloated with fluff. Not this book.

First of all, this book assumes that you know Java. That is rule 1 that many books fail to observe. This book is about wireless Java so it does not waste space teaching you Java. If you want to learn Java, you'll read a book that is written specifically for that - and you'll likely find a great one too. So why redo it in a way that will suffer anyway?

Second, this book gives you useful information, and only useful information. No space is wasted. Every chapter is concise, to the point, and specific. I've never read a book with such a high percentage of useful information. I'll gladly pay about the same price for a 200-page book with 190 useful pages instead of a 1000-page book with 90 useful pages. The presentation is clean, clear, and consistent.

Third, well, the topic is wireless Java, so I'll also tell you that I picked up this book knowing Java but not J2ME, and after reading it I know everything I need to know to writing Java programs using J2ME. I've looked at all the Java wireless books and I truly believe that this is the best one. You'll learn about how J2ME is partitioned, how MIDP fits into CLDC, what parts of J2SE are included and left out, how to write MIDlets and user interfaces, how to work with persistent storage (micro-databases), networking, performance optimization, XML, and security.

The author and his team (because a book does not come to exist by only one person) should be applauded for boldly going against the trend of selling books by weight.

One last note: this is the ONLY book for which I thought even the appendix was useful!

Enjoy it and enjoy trying out J2ME.

5.0 out of 5 stars the best J2ME resource available, May 19, 2003

By	"glschwar77" (Bloomfield Hills, Mi United States) - See all my reviews

After reading the first edition of Knudsen's book, I was able to successfully write a J2ME application that is now being distributed by major cellular service providers. I had no prior experience with J2ME and gained all of my knowledge from that book.

I picked up the second edition as soon as it came out and was extremely pleased with the new information presented. It is a "must have" for anyone interested in learning J2ME in general or J2ME programmers looking to work with MIDP 2.0.

Knudsen explains programming in a clear, thorough manner. The few questions that I could not find answers to in his book (and there were definately only a few), I was able to e-mail the author and received quick, detailed responses.
