Programming - Object-oriented

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of which can contain data and code: data in the form of fields (attributes), and code in the form of procedures (methods).

Think of OOP as building with Lego bricks. Instead of writing a long list of instructions for a computer to follow top-to-bottom, you create independent units (objects) that interact with each other. The Four Pillars of OOP

: It is much easier to manage large, complex software systems when they are organized into objects. Object-Oriented Programming

: You can use classes you’ve written before in new projects through inheritance.

: This literally means "many shapes." It allows different objects to be treated as instances of the same general class through the same interface. For instance, a "Draw" command could look different for a "Circle" than it does for a "Square," but you can call draw() on both. Why Use It? The Four Pillars of OOP : It is

To truly understand OOP, you need to know its four core principles:

: This means showing only the essential features of an object and hiding the complex implementation. For example, when you drive a car, you interact with the steering wheel and pedals (the interface) without needing to understand how the internal combustion engine works (the complexity). For instance, a "Draw" command could look different

: This allows a new class (subclass) to adopt the properties and behaviors of an existing class (superclass). If you have a class "Vehicle," a "Car" class can inherit from it, automatically gaining features like "wheels" and "engine" while adding its own specific details.
