Object Oriented Programing

Object oriented programming is essentially building a program around self-contained collections of data and code to modify that data; this programming model is in contrast to a model that uses function that act on data scattered throughout a program. Object-oriented programming (or coding, as programming is commonly referred to) is an organizational style, but it helps programmers create reusable code because the code to do a specific thing is entirely contained within a single section of code, and to use the code to perform tasks - for instance, creating a menu - involves using only a small number of functions to access the internals of the class. Think of it as a black box that can be easily carried from place to place, and that performs complex actions simply at the press of a button: for instance, a microwave lets you heat food for a specified time limit - say, two minutes - by typing in the time and pressing the heat button. You do not need to know how the microwave operates or why the physics works. In the same way that self-contained appliances simplify life for the consumer, object-oriented programming simplifies the transfer of source code from one program to another program by encapsulating it - putting it all in one place.
