perhaps what would be more appropriate in your situation would be

You can get the same behavior of an abstract class by creating a
class that has a private constructor.
That way it cannot be instantiated directly but can be inherited from.
Right, but you cannot define abstract methods, or implement an
interface and leave some interface methods unimplemented as you could
with a proper abstract class.
