What is Object-oriented programming?

Object-oriented programming (OOP) is a way of writing software by modeling things as 'objects' that bundle data with the actions that work on it. It helps organize large programs into reusable, understandable pieces.

Key things to understand

  • 1Objects combine data (attributes) and behavior (methods) in one unit.
  • 2Classes are blueprints; objects are instances made from them.
  • 3Core ideas: encapsulation, inheritance, and polymorphism.
  • 4It makes big codebases easier to reuse, extend, and maintain.

A class is a blueprint; an object is a specific instance created from that blueprint.
What is inheritance?
A way for one class to reuse and extend the properties and behavior of another.
Why use object-oriented programming?
It organizes complex code into reusable, self-contained pieces that are easier to maintain.
