Whether correctly understood concept - the abstract method?

Question

OOP

1. An abstract parent has an abstract method.
2. The described method is created in one of the descendants.
Does this mean that in the rest of the descendants this method will (should) just be visible with the functionality created in paragraph 2?

Answer 1

Does this mean that in the rest of the descendants this method will (should) just be visible with the functionality created in paragraph 2?

No, in an abstract parent, the method is still empty, and all descendants of this parent are required to implement this method.
