the Java decompiler
Mocha is the Java decompiler. Where a regular Java compiler takes Java source code (a .java file) and produces Java bytecode (a .class file) from it, Mocha does exactly the opposite: it reads bytecodes and converts them back to Java source code. Although the source code produced by Mocha seldom is exactly identical to the original source code (comments, for instance, are lost), it is surprisingly close. It's certainly good enough to enable you to understand or modify the Java program.
