4.11 Recap Of OOP Terminology

My biggest criticism of object-oriented programming (OOP) is the language used to describe the principles, as the terms are difficult to remember and understand.

In this step you will review the terms and join a conversation about the concept you found most difficult to understand, so that you can provide an alternative description.

You have learnt the following terms during this course:

• Object: the data and functions required to model something in code

• Class: a blueprint for making an object

• Instance: a specific example of an object

• Attribute: a named piece of data stored within an object

• Method: a function which performs a task on an object i.e. tells the object what to do

• Inheritance: a class is able to use all of the attributes and methods from a superclass

• Polymorphism: when a method behaves differently depending on which object it belongs too

• Aggregation: when an object contains an instance of another object

I have provided some brief descriptions for each. I am sure you can do better, though.

Pick a term from the list above and comment on how you would describe it to someone else.
