JD-GUI: Java Decompiler

Searching a good java dcompiler from long time. Tried some like DJ Java Decompiler at previous. It was also good but have to pay money for full version 🙁

Suddenly got another very good Java DeCompiler. The best thing about is, its free 🙂

Its written in C++ and allows an extremely fast decompilation (Yah! you are reading right. It can retrieve source code from a .class file).

Its available in linux, mac as well as windows also. Download JD-GUI from here. A humble request don’t use it for any cracking purpose 😉
