: It is much easier to manage large, complex software systems when they are organized into objects.
: Troubleshooting is easier because the code is divided into independent pieces.
: You can use classes you’ve written before in new projects through inheritance. Object-Oriented Programming
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
: 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). : It is much easier to manage large,
: This is about "bundling" data and the methods that work on that data into a single unit (a class) and hiding the internal details from the outside world. It’s like a black box; you know what it does, but you don't need to see the wires inside to use it.
: 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.

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