Protect Jar file source code with exe file (Java) [duplicate]

This question already has answers here: How can I convert my Java program to an .exe file? (16 answers) 开发者_开发百科 Closed 7 years ago.

How would I make a .JAR file open up when I make another file as .EXE?

I have tried many things, but they don't work.

I want this for another way to protect my source code. Kind of like what Minecraft does. You open a .EXE, and somehow the .EXE opens up the .JAR file.

Anyone have any ideas?

To convert to exe, I use JAR2EXE.

However obfuscating your code can deter people who want to access your code. But a determined person would still access it. You can use proguard to obfuscate your code.\

You can access the MineCraft.jar but the code is obfuscated.
