Java Virtual Machine

by Troy Downing and Jon Meyer

Book Overview

The Java Virtual Machine is the software implementation of a "CPU" designed to run compiled Java code. This includes stand-alone Java applications, as well as "applets" that are downloaded and run in... This description may be from another edition of this product.

Very good intro

If you're just entering the JVM aspects - that's a good place to start, I think. The JVM explained in a simple, not confusing manner, the book can easily be read by anyone. Then you might go to read the full "JVM Spec" from Sun. 4 stars for authors spend too much place describing Jasmin ( JVM assembler they wrote ) - tell me, who needs it ? I hardly imagine anybody writing bytecodes in assembly. *Reading* bytecodes is something else, I do it on a daily base - but let's leave the job of creating them to javac.One special "thank you" is for "Appendix A" where all JVM instructions are nicely listed by the function group. I browse it the most.

Not a bad book, but misleading...

This is a good book for those that are interested in learning the bytecode structure of the Java Virtual Machine and its class file structure. It comes with a bytecode assembler, called Jasmin. Some reviewers felt that the assembler is completely useless. I liked having it as it helped me to learn and test my knowledge of java bytecode without having to write an interpreter first.This book is misleading, however, as most books on this subject do a pretty good job of explaining the internals of the Java Virtual Machine. This book does not. If you are looking to understand java bytecode and class file format better, this may be your book. But, if you are looking to get the full explaination of the workings of the Java Virtual Machine (especially if you are trying to write your own), then "Inside the Java Virtual Machine" is a much better book.

good introduction

Compering to others books about jvm this one gives you much more details about functionality of jvm. Looking deeply inside structer of jvm less in just instruction.But one unneeded detail is "jasmin" assembler who needs it no practical apply.

Excellent technical reference!

JAVA Virtual Machine is an impressive technical reference. The book provides a wealth of detailed nuts-and-bolts information relating to Java and the JVM. A Java *assembler*, called "Jasmin", provided with this book makes it especially practical for power programmers.In spite of a variety of typing errors in the text (it is hard for copy editors to stay on top of technology apparently!), JAVA Virtual Machine is a must for every Java hacker's reference library!

Great book on the JVM.

A great book on the Java Virtual Machine! I learned more about how java really works faster than with any of the other fourjava books I own. --Dave Doolin
