Tutorial Details:

A JVM is a simple stack-based CPU with no general-purpose programmable registers. Its instruction set is called bytecode. Code and data are organized in JVM classes (to which Java classes are mapped), but the JVM does not support all Java language features directly. The JVM Specification also defines many verification and security rules. Even so, programming at the bytecode level proves error-prone and risky, as I personally witnessed in Jamaica testing. Also, bytecode programs tend to be longer than other CPU assembly programs because JVM instructions mostly operate on the stack top. Jamaica tries to address some of these issues, adopting a Java-ish approach: it uses Java syntax for class infrastructure declaration and symbolic names in instructions for references to variables, fields, and labels. Moreover, Jamaica has defined numerous macros for common patterns, making it much easier to read and write JVM assembly programs.
