OOPS
Object-oriented programming (OOP) is a computer science term used to characterize a programming language that began development in the 1960’s. The term ‘object-oriented programming’ was originally coined by Xerox PARC to designate a computer application that describes the methodology of using objects as the foundation for computation. By the 1980’s, OOP rose to prominence as the programming language of choice, exemplified by the success of C++. Currently, OOPs such as Java, J2EE, C++, C#, Visual Basic.NET, Python and JavaScript are popular OOP programming languages that any career-oriented Software Engineer or developer should be familiar with.
OOP is widely accepted as being far more flexible than other computer programming languages. OOPs use three basic concepts as the fundamentals for the programming language: classes, objects and methods. Additionally, Inheritance, Abstraction, Polymorphism, Event Handling and Encapsulation are also significant concepts within object-oriented programming languages that are explained in online tutorials describing the functionality of each concept in detail.
High-end jobs with well-paid salaries are offered around the world for experts in software development using object-oriented programming languages. The OOPs concepts described and explained in easy to use, step-by-step, practical tutorials will familiarize you with all aspects of OOPs.

Object Oriented Programming Introduction Object Oriented Programming, also known as OOP, is a computer science term which is used to describe a computer application that is composed of multiple objects which are connected to each other. Traditionally, most computer programming languages were simply a group of functions or instructions. With OOP, every object can handle data, get messages, and transfer messages to other objects. The objects will all act as independent units in their own right, and they will be responsible for carrying out a certain process. Because the objects are not dependent on each other, OOP is seen as…

Object Oriented Programming Concepts Three of the most basic concepts for object oriented programming are Classes, Objects, and Methods. However, there are a few more concepts that you will want to become familiar with. These are Inheritance, Abstraction, Polymorphism, Event, and Encapsulation. In this article, I will be using the class Cats as an example. Inheritance will allow a sub-group to make a connection with the associates of its parent class. For example, lets say the class Cats decides to create a method called purr() and a property named Colorfur. As the name implies, a property is a specific attribute…

Object Oriented Programming As a Paradigm There has been debate about the proper definition to give to object oriented programming. There has also been some debate about the primary idea behind the concept. In a nutshell, object oriented programming is the technique of writing application text that is split into a number of modules. Object oriented programming is a new framework which is much different from the programming methods that have been used in the past. In fact, the concepts which have been created by OOP are so powerful that they are said by some to be creating a new…

Object Oriented Programming Issues There are a number of errors that programmers can make when they are using an object oriented programming languages. One example of this is looking at the type of object instead of the membership it is associated with. When this happens, the advantages of polymorphism and inheritance are weakened. This is just one of the many issues a programmer may face when trying to create an application with an object oriented programming approach. One characteristic of OOP is that it supports what is called code centrality. Code centrality is connected to inheritance. Many critics point out…

The History of Object Oriented Programming The basis for OOP started in the early 1960s. A breakthrough involving instances and objects was achieved at MIT with the PDP-1, and the first programming language to use objects was Simula 67. It was designed for the purpose of creating simulations, and was developed by Kristen Nygaard and Ole-Johan Dahl in Norway. They were working on simulations that deal with exploding ships, and realized they could group the ships into different categories. Each ship type would have its own class, and the class would generate its unique behavior and data. Simula was not…

Object Oriented Programming Overview If you are not familiar with an object-oriented programming language, you will first need to understand the foundation that makes up this paradigm. It is a necessity for anyone who plans on writing code. In this article, I will explain the basic OOP structures in detail. The first thing that you will want to become familiar with is an object. An object is a bundle of software that contains methods and variables. The objects which are found in computer programs will often be used to simulate objects which exist in the real world. To truly understand…

Understanding The Message Concept In OOPs To understand object oriented programming, you will need to become familiar with messages. As the name implies, a message is a process in which software objects will communicate with one another. Because of this, having one object is not enough. An object will work best when it is exists in a large application that is populated by other objects. When these objects interact with each other, programmers will be able to gain a high level of functionality, and the behavior of the system will be very complex. To give you an example of this,…

Understanding Classes Within Object Oriented Programming To fully understand object oriented programming, you will want to be familiar with classes. When you look at the world around you, it will become obvious that many objects are the same type. For example, the car you drive is just one of the millions of cars that exist in the world. In the OOP terminology, the car you drive is an instance of the class cars. Each car will have a state, and it will have behavior as well. However, the state and behavior of one car is not dependent on the state…

Object Oriented Programming Traditionally, programming languages have been divided into two categories, and these are data and procedures which are carried out on data. By itself, data is static. It will not be static when procedures are carried out which can alter it. The functions and processes that work on data are only useful because they can change data. The division of data and procedures which are carried out on it are based on the way in which computers behave. Because of this, it is difficult to push these two concepts aside. Even developers who work with object oriented programming…

The Inheritance Concept In OOPs In object oriented programming, objects will be characterised by classes. It is possible to learn a lot about an object based on the class it belongs to. Even if you are not familiar with the name Maybach, If I told you it is a car, you would immediately know that it has four wheels, an engine, and doors. Objected oriented programming takes this concept to a whole new level. It permits classes to be defined in relation to other classes. For example, sedans, sports cars, and roadsters are all types of cars. In the object…

What is Object Oriented Programming? There are a number of common characteristics which are found in object oriented programming languages. Some of these are the grouping of data and functions, a separation of the interface with the implementation, and the sharing of code. At the most basic level, object oriented programming is a different method of solving problems. Languages which are designed with the OOP paradigm allow programmers to think in new ways. They will also support inheritance, and instead of using function calls, they will use messages. The goal of a computer program is to alter data. What the…

A Object Oriented Programming Lesson For Beginners In this article I will go over object oriented programming in relation to PHP. This article will be especially useful to those who already have a simple knowledge of programming and variables. You should know what a variable is, and you should also know about the different types of variables. When you read this information, it is important to remember that the terms used for other programming languages may be different. It is the overall concepts that you will want to pay close attention to. One of the most powerful aspects of OOP…
The OOP Paradigm Object oriented programming is a concept that was created because of the need to overcome the problems that were found with using structured programming techniques. While structured programming uses an approach which is top down, OOP uses an approach which is bottom up. Traditionally, programming has placed an emphasis on logic and actions. Object oriented programming has taken a completely different direction, and will place an emphasis on objects and information. With object oriented programming, a problem will be broken down into a number of units. These units are called objects. The foundation of OOP is the…
Class-based Object Oriented Programming Class-based object oriented programming is a style that gains inheritance by processing classes as objects. The most prominent style of OOP is class-based instead of object-based. With the class-based OOP system, objects are units that merge states, identities, and behaviors. The foundation and behavior of the object will be characterized by the class, which will act as a diagram of all objects which fall under the same type. The object will need to be constructed on the foundation of a class, and because of this, the object is considered to be the instance of the class…
The Use of Access Specifiers In Object Oriented Programming In object oriented programming, a variable will have a certain range. This range can be defined as the place where it can be viewed. In most cases, there are two simple models that are used, and these are lexically scoped and dynamically scoped. Dynamic scoping is a system which is based on time, and lexical scoping is a system that is based on text. An example of lexical scoping would be the phrase "you get what you pay for." Before you can understand access specifiers, it is important to be familiar…
The Importance of Inheritance Within OOP In an object-oriented programming language that is well designed, a function should be able to have functions that reside inside it. In addition to this, other functions should be processed as input and output as well. When an OOP language uses these features, it will utilize a design that is simple and consistent. This is an important concept that can make the difference between a good programming language and a great programming language. When code is written, the subroutine should be capable of returning a function. When this is done, the argument can be…
