Why don't you split c1 into 2 classes, one with f1, and one with f2, f3. Then c2 can access the first one, and c3 can access the second one.

Another approach here would be to utilise AOP techniques to inject advice and pointcuts that restrict the calling of the necessary methods, based on the type of the calling class.

There's a whole bunch of literature available out there that explains the basic concepts of AOP, here's probably a good jump off point:

Is it really necessary to hide those methods to the other classes ?

When you define something as public, default, etc you dont do it for a specific outside class - you define it as public for all other classes to access, etc
