💡 The Fundamental Pillars of Object-Oriented Programming

Abstraction, Encapsulation, Inheritance, and Polymorphism are the four pillars of object-oriented programming. What do they mean?

1 - Abstraction
This is the process of hiding implementation details and showing only the essential features of an object. For example, a Vehicle class an abstract stop method.

2 - Encapsulation
It involves wrapping data (fields) and methods in a single unit (class) and restricting direct access using access modifiers. For example, private fields public getters and setters.

3 - Inheritance
The process of creating a new class (child) that inherits attributes and methods from an existing class (parent), thereby promoting code reuse. For example, a Car class inherits from a Vehicle class.

4 - Polymorphism
It allows methods to perform differently based on the object they are invoked on. When two types share an inheritance chain, they can be used interchangeably with no errors.
