Essays on Object-oriented Programming

Object Oriented Programming (OOP) is a framework for system design. This framework looks at all datastructures within the system as objects. These objects have attributes that define the object. Methods are used to manipulate data within these objects. Entities are external storages and human users of the system. An entity relationship model is a model that contains objects, methods and entities and their interactions with one another. Contemporary programmers use the OOP framework to design automated systems (docs.oracle.com). In this paper, we examine two key concepts of OOP and present a sample algorithm using OOP concepts. Deborah J. Armstrong proposed some ...

Introduction

Classes and Objects in C++ are the basic concepts of object-oriented programming - OOP. Object-oriented programming - is an extension of structured programming, in which the basic concepts are the concepts of classes and objects. The main difference between the programming languages C and C++ are classes in the latter, and hence the C language doesn’t support OOP.

The Beginning

A Class So a class in C++ is an abstraction describing the methods and properties of objects that don’t exist yet. An object is a concrete representation of that abstraction and has its own properties and methods. Objects, created on ...

Objects (Instances)

Objects are the building blocks of the Java programming language being an object-oriented language. An object is just like real-world objects and their description and properties are described in the object class. An object can be composed of several other objects. The limitations of the properties or the description of an object is based on its class descriptions, its methods and properties set.

An instance of an object is one specific occurrence of the specific object where all the properties and behavior of the object class are inherited. An object reference called the instance of the object is returned ...
