OOP Overview

What this topic covers

Object-oriented programming organizes code around objects that combine data and behavior. It helps when a program has clear entities like users, orders, or bank accounts.

Revision checkpoints

• Learn what classes and objects represent.
• Understand how methods operate on object data.

class -> object -> methods + data

What to remember

OOP is a tool for organizing code. If it makes the model clearer, it is useful. If it adds confusion, simplify.
