Creating non-reverse-engineerable Java programs

Question

Is there a way to deploy a Java program in a format that is not reverse-engineerable?

I know how to convert my application into an executable JAR file, but I want t

Answer 1

As someone said above, reverse engineering could always decompile your executable. The only way to protect your source code(or algorithm) is not to distribute your executable.

separate your application into a server code and a client app, hide the important part of your algorithm in your server code and run it in a cloud server, just distribute the client code which works only as a data getter and senter.

By this even your client code is decompiled. You are not losing anything.

But for sure this will decrease the performance and user convenience.

I think this may not be the answer you are looking for, but just to raise different idea of protecting source code.
