Let's all welcome Jonathan Knudsen, author of "Wireless Java: Developing with J2ME, Second Edition". In honor of Jonathan being here we are giving away 4 copies of his book to four lucky winners who participate in this forum. Jonathan's book has gotten great reviews both on amazon and from your friendly reviews here at JavaRanch. Mark Spritzler gave the book 9 horseshoes and had this to say: "The book is very easy to read, you won't find yourself re-reading a paragraph because you didn't understand. Jonathan has a very smooth elegant writing style that not only instructs you, but it keeps you reading on. I didn't want to put it down, well except for the strong urge to start programming."
So say "hi" to Jonathan and start a new thread with your questions and comments.
Wow, I'm quoted. Welcome Jonathan, I am really glad you could help us and do this great book giveaway. I am positive that whoever wins your book will find great uses for it. I mean a coaster, coffee table leg, booster chair. You know that sort of stuff. Just Kidding. Actually as you read in my quote above, you will not have time to use this book for anything else other than coding and making the reader a great J2ME developer. Mark
From the brief descriptions and afew comments I have read, this sounds like a great book for budding J2ME programmers/developers. What I would like to know though, is how will this book benefit us/me with the next generation wireless applications which seem to be on an express train at the moment? How could you/and I keep up with the progress and speed in which the technology seems to be heading? Does this book just focus on the grassroots or will it put you on the express train for J2ME? I am J2SE 1.4, can I step straight into J2ME? Would love to hear your comments Jonathan/or anyone else who is knowledgeable in this area? P.S. Being an Australian, am I eligible for the book promotion?
Hi Jonathan, Welcome! I am promoted to the J2ME moderator status today so that I can greet you as the forum host here. Sorry we missed each other during JavaOne. But I enjoyed reading your JavaOne Today articles! cheers

Yes, one of the strengths of J2ME is that it allows 3 million existing Java developers go leverage their skills (both API and design patterns) to build brand new applications. Jonathan's book is an excellent introduction to J2ME if you already have some Java knowledge. It is cutting edge too. The second edition covers both MIDP 1.0 (already available on millions of handsets) and MIDP 2.0 (Just available this month from leading vendors such as Nokia).

As far I know MIDP 1.0 is not supporting floating point. I find this especially difficult when programming culculation / fomular based application. Does the newly launch MIDP 2.0 support foating point ?
Welcom to the Ranch, Jonathan. I'm sure you are very busy, so we appreciate the time you are taking to answer our questions. So far, I have been somewhat disappointed with my exploration into J2ME since my intended target platform has been PDAs, as you have seen in the thread that I resurrected. I can relate to the fact that J2ME seems to flourish more on phones than on PDAs. Currently, I don't think I'll be developing for phones, but I'll keep J2ME in mind if any opportunities arise. I'm still interested in learning more, so once again, thank you for your time to answer questions here at the ranch. Layne
