Is there anyway to make it not possible to extract the classes?

What would be the point of that? It would make the jar file useless.

Suppose you gave a program of you to somebody, you wanted them to run it, but you wouldn't want them to see the classes in the jar. You know what I mean?... Just Curious ...

I thought that's what you meant. Well, if one computer program (the Java classloader) can open the jar file (to execute the classes in it) then another computer program can also open it.

And since the jar file format is specified to be equivalent to the zip format, and there are plenty of programs available that are able to open zip files... draw your own conclusion.
