Is there any way from which i make sure so that no can access the resources from my jar file either the class files or images etc.

You can make it harder to get your resources, but you can’t make it impossible. That’s not a Java problem, by the way, but a general one of distributed software. In order to access your resources, your program (or in the case of Java the runtime environment) must be able to unpack them. Even when you encrypt them somehow, the program needs to include the decryption key and the decryption algorithms. A determined user can find these through reverse engineering, and use them to get your resources.
