Create subclass but doesn't need 1 superclass property
显示 更早的评论
My superclass has property [a, b, c]
If I decide to inherite a subclass from it, but doesn't need the superclass property [C],
is there a easier way to achieve it?

- Ignore the fact that the superclass has the property by not using it in any of the subclass methods.
- Split the superclass into two classes, one with properties A and B and one with property C. Modify existing subclasses to inherit from both and write your new subclass so it only inherits from the former.
- Rethink your inheritance hierarchy: if all superclass objects must have property C and your subclass cannot have property C, your subclass would violate the Liskov substitution principle.
