The protected keyword is really very different in java and c# as in java it allows access to other members of the same package and to subclasses and in c# it only allows access to subclasses. Yeah?

The internal keyword in c# restricts access to the assembly, but this has no bearing on the namespace.

Java really has a fouth access modifier, the 'not-specified' access modifer which resricts access to the package. In many ways I think this is most useful one.

By not allowing us to restrict access to classes in the same namespace/package, doesn't this more or less defeat the point of putting them in different namespaces in the first place?

I feel i must be missing or misunderstanding something...
