A guide to using Java for Wireless applications, containing lots of serious code - no fluff. Although Java is popular, the standard edition of Java is much too big and bulky to build 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 book uses the current version of J2ME to give real code for real applications, including extensive coverage of the exciting concept of MIDIlets.
