Object-Oriented Programming Concepts

Object-Oriented Programming (OOP) is a programming paradigm centered around objects, which represent both data and behavior. OOP is widely used in software development due to its modular, reusable, and scalable approach to organizing code.

Key Concepts

• Classes and Objects
  A class is a blueprint for creating objects, defining their properties and behaviors. An object is an instance of a class, with its own set of data and methods to manipulate that data.

• Encapsulation
  Encapsulation is the bundling of data and methods that operate on the data within a single unit, or class. It restricts direct access to some components, promoting modularity and protecting the integrity of the data.

• Inheritance
  Inheritance allows a class (child) to inherit properties and behaviors from another class (parent). This promotes code reuse and establishes a relationship between classes, facilitating a hierarchical structure.

• Polymorphism
  Polymorphism enables a single interface to represent different underlying forms (data types). It allows objects of different classes to be treated as objects of a common superclass, making code more flexible and extendable.

• Abstraction
  Abstraction simplifies complex systems by modeling classes appropriate to the problem, hiding unnecessary details, and exposing only relevant features. It helps reduce complexity and improve code readability.

Why Learn Object-Oriented Programming?

OOP enables the creation of modular, reusable code, which makes software easier to develop, test, and maintain. It’s a foundational skill in many programming languages, including Python, Java, and C++. Mastering OOP concepts allows you to build scalable applications with a clear structure.
