About a question in the follow-up quiz.

Hello, in the quiz after this video the following question is getting asked: Can subclasses override non-virtual methods?

The answer "No" is accepted as correct. But what about an abstract method, which is "non-virtual" and can indeed be overridden?

Or is there some language-finesse I didn't get :-)

Best, Manuel

It might not be accurate to say an abstract method can be overridden, it's probably more correct to say that it must be overridden.

But regarding the wording of this question, I don't think the concept of abstract methods has been introduced at this point in the course, so while you are essentially correct, I don't think the question was intended to include them.
