Inside the Java 2 Virtual Machine

Useful for understanding the internals of the Java class file format.

Nice book should have bought it before

As a developer, I have learned a lot about the use of Java language by understanding what happens behind the scenes. The book is a pleasure to read. It is well written, and organized in a manner that facilitates easy access.

This is the best book one can find if one has to understand thoroughly about the Java architecture and its internals.If one goes through this book,the development in Java would be much more efficient and productive and even provide you with solutions which you thought were not possible before through Java(If you have read those run of the mill books in the market on Java programming).Though the book is really indepth I would recommed that one should read atleast the first 9 chapters of this book,especially the chapter on "The lifetime of a Class" and this is some information you will not find anywhere.It also helps in debugging Java programs as it provides you with instruction sets.

This book is somewhat less terse and succint than other books I've read. I don't have tons of time to read so appreciate short books that get to the point. This book was a little thicker than it needed to be. I like it but "Programming for the Java Virtual Machine" by Engel and O'Reilly's "Java Virtual Machine" are somewhat better books and thinner. PFTJVM has some nice diagrams while JVM has some better explainations on things like exceptions. It might be best to check out these three and pick according to taste.

This is a new book coveres the new JVM internals. First the good points. The book contain some Java applets to illustrate many of the concepts inside it and it is wonderful to working with those applets to understand the underlying idea. However, here comes the bad points. First the book is too thick:) When I read the book, I found many of the same sentences are repeated again and again just like the style in the JVM specification. This style is ok for specification as it wants to be precise but too bad for a introductary book. For example, the class loader delegation model is repeated with equal depth many times in different places of the book. I think the contents of the book can be compressed into half with those duplicate contents being cut off. Another problem is that the illustration has many problems. The arrow lines in many pictures are printed just as a ">" symbol. Besides the typesetting problem of the book, many of the pictures do not help much in the book. Also there are many places where a picture should have been presented instead of just puting some vague statements to clearly illustrate the main ideas but the author didn't put them down.

This book gets a little wordy at times leaving me to think that it could have been a little shorter and still have gotten the job done. However, this is the best and most complete book on the Java Virtual Machine that I have seen. It does a good job at explaining the concepts. A must have if you're planning to write your own virtual machine, or if you are just interested in how it works.

This book is mostly a rehashing of the Java Virtual Machine Specification (which is available online from Sun, or in printed form). I found its reference section to be slightly less intuitively-organized than the JVM spec, and the rest of the book didn't really add a lot of new insight, beyond a semi-guided tour of the Java Class File format. I would've like a much more detailed tour of the really interesting JVM elements: locking/synchronization implementation, JITs, threads, and advanced garbage collection implementations. There's a lot of active research into JVM design, but not a drop of it can be found in here, sadly.

More of an informal specification than a deep dive into JVM internals for a specific JVM implementation. I still learned a lot about the java class file and JVM semantics.The prose is quite repetitive - often the same paragraph will be transposed several times in a row with one sentence difference!

Not many books on the JVM, and this is one of the earliest. I found it useful to get to grips with some deeper Java. It certainly helped me appreciated the languages elegance by viewing how it is implemented within the JVM.I realize the book is seventeen years old and areas such as GC are vastly improved but as a primer I really liked this book.

Delivered on time. Good quality

Great book, even if it 's a bit old.

great book
