J2ME in a Nutshell: A Desktop Quick Reference

by Kim Topley, Robert Eckstein (Editor)

Overview

To the experienced Java developer, J2ME (the Java 2 Micro Edition) looks just familiar enough to be tempting, but just different enough to warrant caution. J2ME in a Nutshellprovides the extra security you need when venturing into programming for cell phones, PDAs and other consumer electronic devices. It gives you the reference material you need for J2ME, together with a tutorial that leverages your existing knowledge and teaches you what is different about J2ME without boring you to tears with details you already know. J2ME in a Nutshell provides a solid, no-nonsense reference to the "alphabet soup" of micro edition programming, covering the CLDC, CDC, KVM and MIDP APIs. The book also includes tutorials for the CLDC, KVM, MIDP and MIDlets, MIDlet user interfaces, networking and storage, and advice on programming small handhelds. Combined with O'Reilly's classic quick reference to all the core micro-edition APIs, this is the one book that will take you from curiosity to code with no frustrating frills in between

Editorial Reviews

The Barnes & Noble Review
How many angels can fit on a head of a pin? Probably more than you could squeeze into the constrained programming environments available on today's handhelds. J2ME is something of a miracle: a complete Java virtual machine for these tiny environments. Master J2ME, and you can program tomorrow's PDAs, cellphones, cable set-top boxes -- you name it.

In J2ME in a Nutshell, Kim Topley focuses on the concepts and classes that make J2ME different from garden-variety Java. (Where J2ME and Java 2 Standard Edition overlap, refer to David Flanagan's excellent Java in a Nutshell: this book complements it perfectly).

Topley introduces the Connected Limited Device Configuration (CLDC), J2ME's foundation for programming wireless devices and PDAs; and the Mobile Information Device Profile, which provides support for user interfaces, networking, and persistent storage. There's coverage of MIDlet user interface development with both high-level and low-level APIs; plus a chapter-length introduction to the J2ME wireless toolkit, which integrates with Sun's Forte Java IDE and provides a cell-phone emulator for programming any J2ME device.

As experienced "Nutshell readers" will expect, Part II of J2ME in a Nutshell offers a complete API quick reference -- clear, well-organized, intelligent, and above all, useful. (Bill Camarda)
