The core of Java technology, the Java virtual machine is an abstract computing machine that enables the Java
platform to host applications on any computer or operating system without rewriting or recompiling. Anyone
interested in designing a language or writing a compiler for the Java virtual machine must have an in-depth
understanding of its binary class format and instruction set. If you are programming with the Java programming
language, knowledge of the Java virtual machine will give you valuable insight into the Java platform's security
capabilities and cross-platform portability. It will increase your understanding of the Java programming language,
enabling you to improve the security and performance of your programs.
The author employs a tutorial approach that provides a detailed look into the central workings of the technology
and teaches the reader how to write real programs for the Java virtual machine. He describes methods for
becoming a better programmer through an advanced understanding of the Java virtual machine and Java
technology.
Programming for the Java Virtual Machine
offers comprehensive coverage of all the major elements of
the Java virtual machine--classes and objects, control instructions, debugging, class loaders, compiling the Java
programming language, performance issues, security, and threads and synchronization. The book provides an
introduction to the Java Virtual Machine Specification (JVMS), with a collection of topics that help programmers
understand the Java virtual machine and the JVMS better. In addition, the book features implementations of
Prolog and Scheme, a language that runs on top of the Java virtual machine, generating Java virtual machine
code as it runs and using a Java virtual machine class loader to load the generated code into the system.
You will find detailed information on such topics as:
