Object-oriented programming (OOP) is a programming paradigm that uses "objects" to design computer programs.

Object-oriented programming may be seen as a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a list of instructions to the computer.

In OOP, each object is capable of receiving messages, processing data and sending messages to other objects. Each object can be viewed as an independent machine with a distinct role or responsibility.
