'''Object-Oriented Programming''' ("'''OOP'''") is a fundamental [[programming]] concept in software development for organizing and structuring code. It has become one of the most widely used approaches for designing and implementing complex software systems. OOP encourages the modeling of real-world entities and their interactions in a logical and intuitive manner, making it an essential concept in modern software engineering.

==History==
 
−
The roots of OOP can be traced back to the 1960s and early 1970s. Early attempts to develop object-oriented languages and methodologies include Simula and Smalltalk. However, it was not until the late 1970s and early 1980s that OOP gained significant recognition with the development of languages like C++ and later, Java. These languages provided a practical framework for implementing object-oriented principles and quickly gained popularity.<ref>https://medium.com/javascript-scene/the-forgotten-history-of-oop-88d71b9b2d9f</ref>

;Objects
 
−
:At the heart of OOP are objects, which are instances of classes. Objects represent real-world entities and encapsulate both [[data]] (attributes) and [[behavior]] (methods) related to those entities. For example, in a [[bank]]ing application, you might have an object representing a bank account with attributes like balance and account number and methods like deposit and withdraw.
 
−
;Classes
 
−
:Classes serve as blueprints or templates for creating objects. They define the structure and behavior of objects, including their attributes and methods. Inheritance allows for the creation of new classes based on existing ones, promoting code reuse and hierarchy.
 
−
;Encapsulation
 
−
:Encapsulation is the concept of bundling data (attributes) and the methods that operate on that data into a single object.
 
−
;Inheritance
 
−
:Inheritance allows one class (the subclass or derived class) to inherit attributes and methods from another class (the superclass or base class). This promotes code reuse and the creation of hierarchies, where specialized classes inherit common functionality from more general ones.
