Want to Write Better Java Programs? Look Under the Hood and See What Makes the Ingenious Java Engine Run!

This in-depth guide to Java's architecture and internals is your key to writing more effective and efficient Java code. By understanding the Java Virtual Machine (JVM),you will gain insights into the inner workings of Java technology that will help you harness the full range of Java's capabilities in your programs.

In addition,this comprehensive volume explains the architecture of the JVM,including the interaction of the Java stack,the heap,the method area,and the execution engine. It includes in-depth discussions of various implementation techniques,such as interpreting,just-in-time compiling,and adaptive optimization. It also describes the behavior of Java threads and the Java monitor.

It also covers garbage collection,including reference objects,the train algorithm,and object finalization. Finally the intricacies of the Java security model are discussed,including type safety,the class loader architecture,class verifier,security manager,access controller,and code signing.

With this guide,you'll understand Java's linking model dynamic extension,and you'll learn how to write class loaders. You'll also uncover the seven steps to writing a platform independent Java program.

My primary goal in writing this book was to explain the Java virtual machine-and several core Java APIs closely related to the virtual machine-to Java programmers. Although the Java virtual machine incorporates technologies that have been tried and proven in other programming languages, prior to Java, many of these technologies had not yet entered into common use. As a consequence, many programmers will encounter these technologies for the first time as they begin to program in Java. Garbage collection, multi-threading, exception handling, dynamic extension---even the use of a virtual machine itself-might be new to many programmers. The aim of this book is to help programmers understand how all these things work, and in the process we hope to help them become more adept at Java programming.

Another goal I had in mind as I wrote this book was to experiment a bit with the changing nature of text. Web pages have three interesting characteristics that differentiate them from paper-based text: they are dynamic (can evolve over time), they are interactive (especially if you embed Java applets in them), and they are interconnected (you can easily navigate from one to another). Besides the traditional text and figures, this book includes several Java applets (in a mini-Web site on the CD-ROM) that serve as interactive illustrations of the concepts presented in the text. In addition, I maintain a Web site at art ima. com on the Internet that serves as a launching point for readers to find more (and more current) information about the topics covered in the book. This book is composed of all of these components: text, figures, interactive illustra. tions, and constantly evolving links tofurther reading.
