Long on Words, Short on Details • • • • • (bewertet mit 3 von 5 Punkten) Rezension bezieht sich auf: Inside the Java 2 Virtual Machine, w. CD-ROM (Enterprise Computing) (Taschenbuch) As the author himself states, the first four chapters of the book are merely a "broad overview of Java's architecture". The majority of this material should be familiar to Java programmers. I was so bored that I skipped ahead to chapter five. The next five chapters are a little better, but again much of the material is basic Java architecture including class loading, verification, and garbage collection. Finally, in chapter ten the author starts describing the bytecode instructions, but many details are glossed over, left out, or just plain wrong. For example, there's almost no description of how the bytecode verifier checks stack operations, and the description of the multianewarray bytecode when the number of dimensions in the bytecode does not match the number of dimensions of the type of the array is completely wrong. If the author had included a bytecode assembler, such as Jasmin, and had provided exercises, these weaknesses would have become readily apparent. If you're a Java programmer and just want a basic overview of what goes on behind the scenes to allow your Java program to load and run, this book may be adequate. But if you intend on writing a compiler or a JVM, or writing code in bytecode assembly, or just learning what really goes on behind the scenes, I'd recommend one of the other books on the JVM.
