如何在Java Project中隐藏/保护媒体文件夹？

Question

I am a beginner Java developer and I have created an application in Java (Netbeans).

I have used buttons icons, backgrouds for jframes etc. When I built the project, they can easily accessible using WinRAR. Anyone can extract my jar file and see all the images that I have used in my program. Even the images used in jpanel that is not accessible without password.

How can I hide or protect these images?

I have created a .exe file also using Launch4j but still facing same problem. When I right click on the .exe file, its easy to extract my whole program.

To be honest, if someone wants your picture, they are going to be able to get it. One can simply do a print screen. However you can still do somethings.

1. Remove the extensions for the picture files and give them crazy names - this will make it harder for people to find your pictures
2. Encript the files then have the application decript them when loading - I don't know how to do this but shouldn't be too hard to find, for instance you could save the pictures as a byte stream with some alterations then reload it.
3. Save the picture in some archive which only your application knows how to read.

But anyway even with all these things, I still know how one could get a handle to an open JFrame, look through the components, and then could get your picture. IMHO trying to prevent people for getting your pictures is not worth doing.
