Introduction to OOP (Object Oriented Programming)

Introduction to OOP

• Object Oriented Programming (OOP) is a programming language model organized around "objects" rather than "actions".

• The focus of the object oriented programming is data. The object is manipulated to gain the required logic of the program. The object can range from human being to floor or buildings.

• The first step in OOP is to identify all the objects you want to manipulate. Then it is identified that how they relate to each other. This procedure is known as data modeling.

• The identified object is generalized as class of objects and define the kind of data it contains and any logic sequences that can manipulate it. Each distinct logic sequence is known as a method or functions.

• An instance of a class is called as an "object".

• The object or class instance is what you run in the computer. Its methods provide computer instructions and the class object characteristics provide relevant data. The user communicates with objects ‒ and objects communicate with each other with well‒defined interfaces called messages.
