What is OOP?

·         OOP is a design philosophy.

·         It stands for Object Oriented Programming. Object-Oriented Programming (OOP) uses a different set of programming languages than old procedural programming languages (C, Pascal, etc.).

·         Everything in OOP is grouped as self-sustainable "objects". Hence, you gain re-usability by means of four main object-oriented programming concepts.

·         Today, many popular programming languages (such as Java, JavaScript, C#, C++, Python, PHP, Ruby and Objective-C) support object-oriented programming (OOP).

As an example, suppose you wish to write a computer soccer games (which I consider as a complex application). It is quite difficult to model the game in procedural-oriented languages. But using OOP languages, you can easily model the program accordingly to the "real things" appear in the soccer games.

·         Player: attributes include name, number, location in the field, and etc. operations include run, jump, kick-the-ball, and etc.

·         Ball:

·         Reference:

·         Field:

·         Audience:

·         Weather:

Most importantly, some of these classes (such as Ball and Audience) can be reused in another application, e.g., computer basketball game, with little or no modification.
