Object Oriented Programming Introduction

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

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…

HR Interview – A Guide To Using Nonverbal Communication During Interviews

A Guide To Using Nonverbal Communication During Interviews When most applicants go to an HR interview, they are under the impression that simply answering the questions in the correct way will allow them to get the job. However, this is an assumption that is not quite accurate. A number of studies have indicated that your body language will make up over 50% of the factors that will determine whether you will successfully pass the interview. In contrast, your responses to questions will only make up about 7% of what the employer is looking for during the interview. Based on this,…

How To Protect Your Data Warehouse

How To Protect Your Data Warehouse While many data warehouses are used to access and analyze information, some companies wish to place limits on the type of information that a worker can access. While there are advantages to doing this, there are also some disadvantages as well. Generally, a company will not place an emphasis on security until after the data warehouse has been built. Before you set up a security system for your data warehouse, it is first important to understand what function your data warehouse is being designed for. If most of the people who use the data…

C++ Operator Overloading Part 1

In this C++ tutorial you will learn about Operator Overloading in two Parts, In Part I of Operator Overloading you will learn about Unary Operators, Binary Operators and Operator Overloading – Unary operators. Operator overloading is a very important feature of Object Oriented Programming. Curious to know why!!? It is because by using this facility programmer would be able to create new definitions to existing operators. In other words a single operator can take up several functions as desired by programmers depending on the argument taken by the operator by using the operator overloading facility. After knowing about the feature…

Object Oriented Programming As a Paradigm

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

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 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…

Understanding The Message Concept In OOPs

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,…

The Inheritance Concept In OOPs

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…

Object Oriented Programming

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…
