From within protected methods you do not have access to public methods.

This method is accessible from within the class itself and from within all classes defined in the same package as the class itself.

The program has a compilation error because it does not have a main method.

The program does not compile because Circle does not have a default constructor.

The program has a compilation error because we cannot assign radius to radius.

The program will compile, but we cannot create an object of Circle with a specified radius. The object will always have radius 0.
