Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A distinguishing feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated.
OOP is a programming language model organized around objects rather than "actions" and data rather than logic. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data.
Before starting object oriented programming language, you should understand basic concepts of oopl, which are following:
Object: an entity that consists of both data and procedures to manipulate the data.
Class: a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behaviour (member functions or methods).
Abstraction: The process of picking out (abstracting) common features of objects and procedures.
Encapsulation: The process of combining elements to create a new entity. A procedure is a type of encapsulation because it combines a series of computer instructions.
Data hiding: The process of hiding details of an object or function. Information hiding is a powerful programming technique because it reduces complexity and provide security.
Inheritance: a mechanism to reuse code in new program from old program.
Polymorphism: More than one form of function.
Messaging: Message passing is a form of communication used in parallel programming and object-oriented programming.
