I pretty much get the idea that when we export / created the installer after reading to the code.
The person who had the installer and the java class; also the DB, will not be able to edit or view the java code aside from seeing tons of .class file.
~~~~~~
Due to pressure, and me being unable to be 100% sure if I can convert it back to java code; I wonder if any expert can give me a confirmation on my understanding and suggestion?
My intention is to perform unit testing, edit/ view code.
I really appreciate any help provided.
Thank you so much.
Using java decompiler appear to be able to help on this as suggested by @Scary Wombat.
