Course Items
Inheritance Introduction
Inheritance allows us to group similar classes under a more general parent class
Overriding vs Overloading
Adding a method to a Child class that does not exist in the Parent class is called overloading, writing a method of the same name as a method in the Parent class is called overriding
Adding Parent Methods
We can add a method to the Parent class and all Child classes will inherit it
Is-a vs Has-a
The difference between an Objects that has-a Class and is-a Class
Abstract Classes
An Abstract Class is one that is only meant to be used as a parent class and never to be instantiated as an object
The Object Superclass
All classes that do not state a class they extend from, extend from the class Object
The Pet Cafe
Our Cat Cafe has taken off and we've now expanded it to a Pet Cafe. Inheritance can save us some time when remodeling our system
