Is there a tool to reverse engineer a java.class file?

Question

I am in jam. I accidentally rm a java file I have worked on for several days. There is no back up for it. I do however still have the .class file around.

I need some tool to reverse engineer this code. It does not have to be really good tool.

I just need something to remind me enough of what I did and I fill in the rest. Is there such tool ?

http://en.wikipedia.org/wiki/JAD_(JAva_Decompiler), it won't give you clear source back, but it will help a bit. — Victor Sorokin, Jun 06 '13 at 20:10
may be u should see this http://stackoverflow.com/questions/671394/where-can-i-find-a-java-decompiler — nachokk, Jun 06 '13 at 20:12
The question [Java decompiler](http://stackoverflow.com/q/4375037/214178) discusses couple more options and an Eclipse plugin option. — artdanil, Jun 06 '13 at 20:15
It can't help you either, reverse engineering requires skills other than coding java and time spent to return code back double or triple. — Roman C, Jun 06 '13 at 20:25

JD-GUI is pretty good and should help you out.

Ok, thank JD-GUI seems to work I still need to do some work but this is good enough. And yes, I do have source control unfortunately I could not check in the code because it was not complete. This is just a case of the fingers were to fast for the brain. – tadpole Jun 06 '13 at 20:27
