finding a good decompiler

Hi all

Didn't know where to put this and considering I am not exactly a java genius I thought I would post it here. If it is not suited to this forum please could a mod move it to the appropriate location.

I have been playing around lately with proguard which is like a code optimiser thing that makes my code a lot smaller by shortening all the names of classes etc. down to things like a.class, b.class etc. (chopped a good 20 to 25% off the size of the thing)

Could anyone recommend a good relatively easy to use java decompiler so I can see what this proguard thing is actually doing to my code? Would that even be worth it or will it not give me a good enough view of what proguard is actually doing? I have heard that decompilers don't always give back great results (never tried using one before :p).

Hey dude. Thanks for the response. That was quite a funny thread actually.

I am not trying to do anything illegal here. Just wanting to make sure I know exactly what proguard is doing to my code. I would never decompile someone else's code without permission.

I actually found quite a nice simple easy to use decompiler with a fun little GUI. It decompiles a particular class and then provides the rest of the related classes in a nice neat little tree hierarchy sort of like an IDE. I think it may even be the one you mentioned in that thread you referred me to.

The standalone is called jd-gui and you can get it here:

There is an eclipse plug-in available too but I really didn't want to bother integrating something into eclipse just yet if it didn't work I prefer to have it in a nice neat directory I can expunge. :p

This thing is wicked fast too. Cross platform as well, foudn one earlier that looked nice but it was Windows only :(

HA ! :D its actually really funny! :D:D:D
