Can i hide JavaScript code of my application?

Hello Sir, I have just learned Java language and on the basis of that I have been writing programs for Java applet for my site. I would want hide the source code of the site or the application that I am creating from the people who would be viewing my site. Well, is it possible to hide the source code simply or is there a very complex method for doing so. I don’t want my hard worked code for my application being copied by others without my permission or my efforts to be stolen by someone else. It would really be helpful if you help me out.
