About this Item

The Java Virtual Machine is the software implementation of a "CPU" designed to run compiled Java code. Using the Java Virtual Machine (JVM) makes it possible to develop additional syntaxes for expressing the problems you want to solve and gives more control over the performance of your application. This text is a comprehensive programming guide for the Java Virtual Machine. Providing an overview and reference of the JVM, it enbles users to create their own implementations of the JVM or write their own compilers that create Java object code. The book is divided into two sections: the first includes information on the semantics and structure of the JVM; the second is a reference of the JVM instructions, or "opcodes." The programming guide includes numerous examples written in Java assembly language. A Java assembler is provided with the book, so the examples can all be compiled and executed. The reference section offers a complete description of the instruction set of the VM, and the class file format including a description of the byte-code verifier.

About this title

Synopsis

Covers the information Java programmers need to understand Java Virtual Machine (JVM), the platform-independent engine used to run Java applets and applications. The chapters offer an overview of the semantics and structure of JVM, a complete description of the instruction set and the class file format, and a reference guide to JVM operation codes. Accompanying disk contains code for examples from the book as well as Jasmin, a Java assembler. Annotation c. by Book News, Inc., Portland, Or.

Review

This book is a comprehensive programming guide for the Java Virtual Machine (JVM). It gives the reader a strong overview and reference of the JVM so that they may create their own implementations of the JVM or write their own compilers that create Java object code.

Perhaps the most important reason for learning about the Java Virtual Machine is that it gives you additional tools for solving programming problems in Java. The Java architecture is very open -- its easy to add programatic extensions to Java, once you have learned the basic rules of the Java Virtual Machine. And the Java Virtual Machine is portable, so you only have to write the extension once.

So if you don't like how a particular feature of the Java language works, why not create an extension library which operates in the way you need it to? Its not as hard as you might think, and this book gives you all the details you need.
