Hello guys, am making a desktop application using javafx and after making the exe installer with inno and wix.
the problem is after installing the program everithing is working properly but when you go to source file all my classes are there intact so it can be changed easyly. HOW CAN I HIDE them or encrypt it so even if you through you can't see the really source codes?
any idea please?

When you create your jar file it's optional whether you include the source code or not. The source code is not needed to run the app, so don't include it.
