How to install Jad?
Solution 1:
The JAD Java Decompiler is a handy tool for Java developers, both for academic use and for recovering your own code on those (hopefully) rare occasions when you lose the source but have the .class files.1

To install it, you can download it Here. I recommend that you get the static binary.
It's a 32-bit binary, so you may also want to add the install ia32-libs if you get any problems...
sudo apt-get update
sudo apt-get install ia32-libs
Also move/copy it to something in the path, like /usr/local/bin, so you can run jad
