Preface - Wireless Java Developing with J2ME, Second Edition
|
Preface
This book describes how to program mobile telephones, pagers, and other small devices using Java technology. It is about the Mobile Information Device Profile (MIDP), which is part of Java 2 Platform, Micro Edition (J2ME). It is concise and complete, describing all of MIDP, as well as moving into several advanced topics like XML and cryptography.
This second edition covers MIDP 2.0, which includes many exciting enhancements. Three entirely new chapters have been added, and the rest of the book has been meticulously updated.
Who are You?
You're probably reading this book because you're excited about building wireless applications with Java. This book is aimed at people who already have experience programming in Java. At a minimum, you should understand the Java programming language and the fundamentals of object-oriented programming. Some chapters delve into subjects that in themselves could occupy entire books. These chapters include suggested reading if you want to get up to speed on a particular subject.
If you are unfamiliar with Java, I suggest you read an introductory book or take a course. Learning Java, Second Edition (O'Reilly 2002) is a good introduction to Java for programmers who are already experienced in another language such as C or C++.
