20. Decompiling Java Class Files    coderanch.com

Well, I'm not sure how you'd even read the bytes of the class file without some sort of "software". It's tempting to start to list hopelessly impractical and silly low-level procedures for doing this. But to save time, I'll assume you're willing to at least use basic tools provided with Sun's own JDK - namely, javap. You can use this to ...

Firstly am not sure if the decompiled version will be exactly same as that of the original file.

27. Decompilation of java class file into source code    forums.oracle.com

Decompilers don't produce very readable code normally. You can use obfuscators which make the decompiled code even harder to read. But ultimately, this is silly.
