Extract of sample "Object Oriented Programming"

Download file to see previous pages The research paper "Object Oriented Programming" talks about main concepts and principles of the object oriented programming paradigm and about its application to computer software or computer applications design.
In OOP, the represented objects have specific data fields such as rows and columns in the design of databases. These fields are used in OPP as characteristics of an object that is presented through a programming language with object oriented attributes. In addition, objects within object oriented programming are represented via specified methods or procedures which are used to ensure that these objects are orderly and consistent depending on the purpose of the design or programming.
When programmers design computer software or computer applications, they achieve this by methods which cause objects to relate or interact with one another. Each object in this form of interaction is referred to as an instance of a particular class of objects.
Classes in OOP represent concepts. For example “Girl” is a class within which the aforementioned objects fall. This illustrates that a class is used to capture the properties that are shared by objects in the process of object oriented programming. Therefore, classes are normally instantiated from the objects that are represented by a program design. In OOP, classes are visible within the source code of the program and this code is normally not duplicated. Also objects play the role of activating a program that is currently running as a result they occupy memory locations. Furthermore, a set of operations as presented within the class are owned by objects which means that objects in OOP own a copy of specific data that is held within the program. When a specific class within a program is a subtype of another higher level or general class, the subtype class in OOP is said to be inherited from the general class (Hadar and Uri 43). The subclass therefore inherits both member functions and the data members of the base class. In object oriented programming, inheritance particularly refers to the method of reusing a specific code that is held by various objects with an aim of establishing a lower level or subtype class below a general class. The creation of subtypes however depends on the supporting platform of the programming language that is used to design or program the application. The general classes in inheritance are referred to as base classes and it is from these classes that the subtype classes inherit various attributes. Base classes are also referred to as parent classes or super classes (Pefkaros 219). The subclasses that are derived from the parent classes are therefore referred to as child classes or derived classes. This illustrates that the patent and child classes are related within a structure which leads to a hierarchy. Encapsulation is a concept and principle in object oriented programming in which the designer of a program hides the manner in which an object behaves from the approach of implementation. Encapsulation also includes separation of the looks of an object or it appearance from the methods through which its behavior is implemented. Encapsulation emanates from the fact that objects within a program have well defined interfaces (Ramsin and Richard 31). These are the publicly accessible methods and fields. Therefore when information about objects is hidden below or behind a specific interface, it is then said that the design of a program has implemented encapsulation. This situation is also referred to as information hiding. It therefore is notable that in object oriented programming, programmers use interfaces as the most effective way through which behavior of objects are ...Download file to see next pagesRead More

Object-Oriented Technologies

... 05 July 2007 Object-Oriented Technologies Object-oriented technologies include such broad areas of research as software engineering and programming languages, oriented programming and development, human computer interfaces and grid computing. In object-oriented technologies, a programmer determines not only the data structure and type of technology but technological structure and functions which can be applied to different environments. According to Meyer, the object-oriented techniques are 'classes, objects, genericity, concurrency, persistence and design by contract" (776). The main advantage of object-oriented technologies is that they allow to add some new technologies but do not need to change the object. "An object... such features...

...Running Head: Object Oriented Metrics Introduction An object oriented matrix analysis and design ofsoftware has many advantages. Some of these advantages include readability, decomposition of problem into easily understood object and finally the software helps any modification that may be included. The development of object oriented metrics is a very complex design that requires a number of systematic approaches or steps. Therefore for a good OO to be installed or programmed, a guideline has to be followed. The most important thing to be considered first is the Object...

Object Oriented Programming

...Object Oriented Programming OOP is an acronym for Object Oriented Programming. Traditionally, a computer program was seen as a collection offunctions or procedures or simply a list of instructions whereas with the advent of Object Oriented programming, each program may be seen as comprising a collection of individual units, or objects, that act on each other. In simpler terms, it is a type of programming in which programmers define not only the data type of a data structure, but also the types of...

Object oriented development

...OBJECT ORIENTED DEVELOPMENT PHP INTRODUCTION Historically, but not so long ago, there were several techniques and methodologies developed to appropriately write computer programs in a manner in which codes are manageable and easy to understand. The traditional or unstructured programs were replaced by a much better, more reliable procedural programming based on the concept of procedure call . Procedures are also known as routines, subroutines, methods, or functions, a technique to group sets of codes with specific purpose into one. The aim of procedural programming is to enable any given procedure within a program to be...

... of the of the of the Object Oriented Programming INTRODUCTION A Computer Program is a series of instructions that tells a computer what tasks it needs to perform and in what sequence. These programs are often written in high level languages that are further converted into machine language to make the instructions understandable for computers. A program or a comprehensive set of instructions that is designed to achieve a particular objective is referred to as a function or a method. These functions always work on related data. There are two paradigms that are followed to write computer programs: ‘procedural’ or ‘object oriented.’ Procedural paradigm comprises of creating a set of functions or modules and is sometimes referred... to as a...

...Objects and Object Oriented Programming Introduction as used in object oriented programming is a group of things or objects that have the same characteristics. A class contains many objects that share all things in common. Objects in a certain class are the instances of that class. Abstract class This is a class that states explicitly virtual methods and it is labeled as abstract and thus no objects can be created in it. Opposite of this is a concrete class which allows for instantiation (Phillips, 2010). Local class This is a class that is defined inside another class. Class in which it is found is called the enclosing class. The local class is never instantiated together with its enclosing class and neither is it associated... the...
