ITPEC FE Morning October 2019 Question 47
ITPEC FE Morning October 2019 — Question 47 of 80
Inheritance in OOP — using attributes and functions of a parent class in a subclass.
Inheritance allows a subclass to reuse the attributes and methods defined in its parent class.
Why not others:
- (a) Encapsulation — hiding internal implementation behind an interface
- (c) Override — redefining a parent method in a subclass (a mechanism, not the concept of gaining access)
- (d) Polymorphism — one interface, different behavior depending on object type
Key rule: Inheritance = "subclass gets parent's stuff." Override and polymorphism build on top of inheritance but are separate concepts.
