Inheritance (OOP) (OCR A-Level Computer Science): Flashcards

A new class inherits attributes & methods from existing class

Code reuse & hierarchical relationships between classes

Existing class from which attributes & methods are inherited

Inherits from parent, can have own unique attributes/methods

Child uses parent's attributes/methods without rewriting code

Child provides new implementation of parent's method

Allows child to access methods/attributes from parent class

Pass parent class as parameter to child class

Shared behaviour in parent reused by all child classes

Child classes extend/customise behaviours easily

Class hierarchies mirror real-world relationships clearly

Forgetting super() leads to incomplete initialisation
