Learning Wireless Java is for Java developers who want to quickly come
up to speed and create applications for the Micro Edition audience. This
book covers the Connected, Limited Device Configuration and the Mobile
Information Device Profile (MIDP), both currently available from
Javasoft. The CLDC contains APIs for small devices that are constrained
by both memory and processing power. MIDP builds on top of the CLDC and
adds APIs specifically for devices such as mobile phones and pagers,
allowing programmers to create MIDlet applications.
This book offers a solid introduction to J2ME and MIDP, including an
explanation of the J2ME Wireless Toolkit, the MIDlet lifecycle methods,
the Java application manager, and the CLDC and MIDP constraints. In
addition, we cover the javax.microedition.io, javax.microedition.rms,
javax.microedition.lcdui, and javax.microedition.midlet classes, as well
as the modified java.lang, java.io, and java.util classes. Discussion
centers around building safe, compact applications with the
sophisticated graphical interface, database, and networking capabilities
that the J2ME supports. In addition, this book also shows you how to
download your applications to the latest J2ME-enabled devices, including
the Motorola i50x and i85s phones and upgraded Palm handhelds.
