Object-Oriented Programming Concepts
Object-Oriented Programming (OOP) is a paradigm centered on classes and objects.
Summary
Object-Oriented Programming (OOP) is a paradigm centered on classes and objects. It includes encapsulation, which bundles data and methods within classes and restricts access using modifiers; inheritance, allowing child classes to reuse parent class properties and methods; polymorphism, enabling different method implementations through overloading and overriding; and abstraction, which hides complex details via abstract classes and interfaces. OOP promotes modular, reusable, and maintainable code structures.

Object-Oriented Programming (OOP)
OOP is a programming paradigm based on objects and classes.
Main Concepts:
1. Encapsulation Encapsulation is the bundling of data and methods that operate on the data into a single unit (class). It also restricts direct access to some components using access modifiers (private, public, protected).
2. Inheritance Inheritance allows a class (child class) to inherit properties and methods from another class (parent class). This promotes code reuse.
3. Polymorphism Polymorphism allows methods to have different implementations. Types: - Method overloading (same method name, different parameters) - Method overriding (child class provides its own implementation)
4. Abstraction Abstraction means hiding complex implementation details and showing only the necessary features. This is usually done using abstract classes and interfaces.
OOP helps make code more modular, reusable, and easier to maintain.
