A solid introduction to working with the Mobile Information Device Profile (MIDP), which contains the APIs designed specifically for writing applications that need to run on wireless and embedded devices. It includes reference material on the core and javax.microedition classes, as well as on the classes specific to the various wireless platforms the J2ME supports.

Although Java is incredibly popular, the standard edition is too big and bulky for building applications for wireless devices, such as the Palm or cell phones. Thus Sun has released "Java 2 Micros Edition" (J2ME). J2ME has the potential to be as revolutionary in the wireless space as Java has been in the server space. This is the first book that uses the current version of J2ME to give real code for real applications.

Wireless Device Programming with Java 2 Micro Edition assumes readers are motivated to build the next generation wireless application by leveraging the J2ME technology. The book provides commercial-quality code and examples primarily based on the industry-leading Motorola phone emulator.

Sams Teach Yourself Wireless Java with J2ME in 21 Days captures the growing beginner and hobbyist market interested in building wireless applications.

Covers the Mobile Information Device Profile 2.0 and its security features and user interface, discusses the media and game APIs, and explores performance tuning and cryptography.
