Like i said on title, Is there any complete decompiler for .class files? (c/p :P)

I know that is illegal, but, i still wanted one :D.

I have searched and found some programs that are decompiling the .jar file, but, some names are just "a" or something, so its impossible to recompile.

 

If someone knows something please tell me, if there is no way to something like this exist please inform me and tell me the reason, just to know and stop seaching.

Rename a .jar to .zip. Dezip it after.

 

After that all classes are able to be seen with a decompiler.

 

I don't think you can reverse engineering the totality of a source without handmaded work. I'm perhaps wrong as I used only one free decompiler to see L2J 0.4.1 source code. Some parts of code were just off the main classes.

 

I have to add different decompilers don't give the same result

If class/function/variable names are making no sense, it means that the code has been obfuscated. Thats a commonly used technique against decompiling.
