Answer 1

I'd be willing to bet that a class like Hello.java would be easier to recode. Sounds like you are just beginning. Don't bother with a decompiler - it will be more confusing for you than rewriting.

Answer 2

Yep - you need a decompiler - I recall using something called Mocha, I think. It's not perfect but it'll help. If the class has been obfuscated, though, the results'll be nearly useless.

Answer 3

Yes, you can decompile your hello.class file to hello.java.
In fact you can decompile any .class file...

For details of decompilation process, go to :

http://en.wikipedia.org/wiki/Decompiler


Many decompilation tools are available in market...

However for your ease, you may try any one of these.

Installing and usage instructions are written there.
