Direct execution of Java byte code is possible thanks to a Java extension to the ARM processor core by ARM Ltd., Cambridge, England. Known as Jazelle, the new Java acceleration feature initially ...

How to use the javap command. Most users of the javap tool are interested in decompiling a class and viewing the disassembled bytecode. Here’s how to use the javap tool to view bytecode instructions:.

For example, as a post-compilation step you could massage the .class data to make the byte code either harder to read when decompiled or harder to decompile into valid Java code (or both).

All of these have been translated into bytecode, which is basically the instruction set for a virtual, stack-based computer. (Because some chips also have a Java bytecode instruction set, it also can ...

The Java platform uses a third alternative, bytecode. With bytecode, a high-level program is translated into an intermediate form that can run on various hardware platforms.

For example, the Java byte code language is fundamentally a stack-based language, and mounting a stack-based language onto a register-based core is quite a challenge. Nor is Java technology ideal for ...

Java byte code is not optimised for a particular processor but in the phone world everything is ARM-based. It's a bit inconvenient on the compile side but you can still use Java,” said Ken ...
