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:.

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.

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 ...

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).

Java programs will run without a main method. Semicolons can be optional. Hundreds of extra classes are imported automatically. Exception handling is optional. No need for javac. With typical, ...
