Object Oriented Programming

For all the beginners in object-oriented programming language , these are the few concepts that you should learn before coding . here you are going to get familiar with objects, classes, inheritance, interfaces, and packages. The prime focus of these topics will be to make you understand these topics relationship to the real world, while simultaneously providing an introduction to the syntax of the Java programming language.

OOP is philosophy of designing. It Full form is Object Oriented Programming. Object-Oriented Programming (OOP) uses a different concept than old procedural programming languages (C, Pascal, etc.). Everything in OOP is based on the concept of "objects". Hence, anyone can gain re-usability by means of four main object-oriented programming concepts.

OOP is nowadays widely accepted as being far more flexible than any other computer programming languages. The three basic concepts as the fundamentals for the programming language in Object Oriented Programming are: classes, objects and methods. Additionally, Inheritance, Abstraction, Polymorphism, Event Handling and Encapsulation are also significant concepts within object-oriented programming languages.

Object-oriented programming (OOP) is a programming paradigm using "objects" – data structures consisting of data fields and methods together with their interactions – to design applications and computer programs. Programming techniques may include features such as data abstraction, encapsulation, messaging, modularity, polymorphism, and inheritance. Many modern programming languages now support OOP, at least as an option.

There were some drawbacks in procedural language to overcome those there was object oriented language brought in existence. structured programming uses an approach which is top down approach , OOP uses a bottom up approach. Traditionally, programming has placed more emphasis on the logic and actions of program.

The Object oriented programming has turn course of action on objects and information. In object oriented programming, a problem will be broken down into a number of units which are called "objects". The Objects are well defined, and they are interacted within the system in a number of different ways. Various advantages are to be found with usage of the OOP paradigm, and some of these are easier maintenance, better and advanced analysis of programs that are complicated, and the reusability of code .

There are a number of programming languages that implements OOP, and some of them are Java, C++, Simula , Smalltalk , ruby ,JADE, Effiel. Data modeling is the one concept with which we are got to be familiar. Before you can constructing an object oriented system, we would first need to know the objects within the system and determine the relationships between them , which is called data modeling.
