Enterprise J2ME Developing Mobile Java Applications [Electronic resources] نسخه متنی

Code Examples

This book uses complete example applications to demonstrate design patterns, best practices, and important API usages. Since this book discusses a wide range of technologies, innovations and application scenarios, it is impractical to cover everything within a monolithic example. Instead, I decided to develop several small to midsize samples, each focusing on a particular topic. This approach allows the readers to partition the learning task and read one part of this book at a time.

The source code is presented in easy-to-digest segments that are relevant to the discussion text. Nonessential parts of the code (e.g., exception handling, importing packages) are often deliberately omitted from the listings for clarity. Hence, the printed listings are sufficient for understanding the ideas but are not directly runnable code. For readers who want to test and play with the code, the complete source code packages and build instructions are available for download from this book's Web sites: Chapter 3).
