Classes
A class is an abstract grouping of objects that are similar to each other.
- For example, in an online clothes shop, the class "items of clothing"
encompasses all objects that are for sale.
Objects of a class can all be operated on in the same way.
- For example, all items of clothing, whether pants or shirts (or something
else) have a price.
Classes can often be identified by looking for nouns in a problem
description.
