Introduction to Object-Oriented Programming

beginner
1 min read

Object-Oriented Programming (OOP) is a programming paradigm that organizes code around objects rather than functions and logic.

Why OOP?

  • Models real-world entities naturally
  • Promotes code reuse through inheritance
  • Makes large programs easier to maintain
  • Encapsulates data and behavior together

Core OOP Concepts

  • Classes and Objects
  • Encapsulation
  • Inheritance
  • Polymorphism
  • Abstraction

OOP vs Procedural Programming

  • Procedural: Step-by-step instructions (C-style)
  • OOP: Interacting objects with responsibilities

Example Thinking

Instead of writing functions that operate on data, you create objects that know things (data) and do things (methods).

Key takeaway: OOP organizes code around objects with data and behavior — it models real-world entities naturally and promotes code reuse through inheritance.
