How to edit .class files in Eclipse

I decompiled a Jar file and got the following files

Jar
|+--.classpath
|+--.project
|+-- gh
|+-- org
|+--META-INF
|+--Cert.ser

I used the jar xfv command tool in decompiling the jar file...

I only see class files in this folders...pls how can i edit them for recompilation...since i'm not able to see the .java files in it...

I use Eclipse IDE...

Thanks

Class files are compiled - in other words you don't edit them, you edit the source .java files and compile those into .class files. Seems the jar you have does not contain the source code. I don't know the goal - but I'd advice against reverse engineering.

Thanks for your help..
