Object-Oriented Programming
Definition
A programming paradigm based on the concept of "objects", which can contain data and code.
Deep Dive
Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects," which can contain both data (attributes or properties) and code (methods or functions) that operate on that data. The core idea is to model real-world entities or concepts as objects within the software, encapsulating their characteristics and behaviors into self-contained units. This approach emphasizes principles such as encapsulation (bundling data and methods within an object), inheritance (allowing objects to inherit properties and behaviors from other objects), and polymorphism (allowing objects of different classes to be treated as objects of a common type).
Examples & Use Cases
- 1Designing a `Car` object with attributes like `color` and `make`, and methods like `start()` and `accelerate()`
- 2Creating a `User` class in a web application with properties like `username` and `email`, and methods like `login()` and `logout()`
- 3A `Shape` class with child classes `Circle` and `Square`, each having its own `calculateArea()` method.
