Wireless Java Programming With J2ME by Yu Feng , Dr. Jun Zhu (Sams)

J2ME. The next frontier of Java technology. The first book was written by Eric Gigure. It was only a reference for J2ME with CLDC in mind as MIDP was under construction at that time. This book is written straight from the trenches. It is a great feast for the coders who want to sully their hands with code.
The book is nicely structured in three parts. Part I talks about Wireless applicatons: how Java is getting into the wireless area, what are the basics needed for J2ME programming, etc. In Chapter 4 , the authors have explained MIDP in detail.
Part II is the core of this book. The authors have covered everything on components of UI for wireless devices. Use of high level and low Level API for application development is explained in detail with lots of code. The use of XML in the wireless application chapter gives an idea of what is possible in the future. The data synchronizatiuon techniques and network programming chapters show the real reach of J2ME. The biggest plus point of this book is the chapter on MOTOSHOP, the application for which Yu Feng won the Motorola contest. The entire chapter is dedicated to the application.
In Part III, CLDC and MIDP class liabraries are given along with very, very good information about DOCOMO's I-mode which made J2ME so popular.
This book is the icing on the cake after Eric's book. Developers who like to play with lots of code will love this piece. The book is for Intermediate to Advance Developers.
