Besides touring the inner workings of expert Java Virtual Machine (JVM), Programming for the Java Virtual Machine provides a guide to Oolong, a low level assembly language for Java. Java verification process, which allows the JVM to check whether a given Java class file. It is safe to run, receives detailed attention as do the debugging techniques, Java class loader, and content. Class file. The book then offers a thorough explanation of how the elements of Java language is compiled into bytecodes, illustrated with Oolong. In a special section devoted researcher, the author shows how other programming languages can be coded in Oolong for use with the JVM, including Scheme, Prolog, and C + + templates. This shows that assembly language does not disappear on the Java platform, but that he can extend the functionality and performance of your Java programs.
