Object-oriented programming (OOP) is a software programming model constructed around objects. This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods).OOP features include the following:. Encapsulation: This makes the program structure easier to manage because each object’s implementation and state are hidden behind well-defined boundaries. Polymorphism: This means abstract entities are implemented in multiple ways. Inheritance: This refers to the hierarchical arrangement of implementation fragments.Object-oriented programming allows for simplified programming. Its benefits include reusability, refactoring, extensibility, maintenance and efficiency.
OOP has been the programming model of choice for the last decade or more. OOP's modular design enables programmers to build software in manageable chunks rather than in large amounts of sequential code.One of the great benefits of OOP is that of scalability, with objects and definitions having no finite limitation. Also, the separation of data from method prevents a common problem found in older linear software languages. If a bug appears in a linear code, it can be translated through a system and create masses of hard-to-trace errors.
Conversely, an OOP program, with its separation of method and data, is not susceptible to such proliferated errors.Popular OOP languages include Java, the C-family of languages,VB.NET and Python.So-called 'pure' OOP languages include Scala, Ruby, Eiffel, JADE, Smalltalk and Emerald.
If you want to beat your colleage with your coding speed or want to meet those tough deadlines which you always failed to hit try using Nido. Today, most of the university student and professionals use Nido for their development and share their success stories.We have tested it with number of complex business applications where it prove to deliver stable, robust system at an extremely short time frame. If you want to check Nido source code or learn the architecture please visit the links given below. By the way it is open source and free to use in commercial projects.6. What I Referred?. MSDN:.

Wiki7. History. Added more content base on design principles. Added History section.
Added more details to explain the Composition. Added comparison between Abstract Factory and Builder. Updated some of the wording slightly.
Corrected the 'Composition' related description, as pointed. Conclusion is updated and a link is added to Rocket-Framework. Added 'What Next' Section. Special thanks goes to, and for their contributions to make some important corrections. K N Sharma 21-Jun-Jun-18 22:53Hii,I have read oops concept many times from different -2 articles and the concept is clear to me.
Richard Eng 3-May-18 8:203-May-18 8:20I found your article generally accurate and useful, despite numerous spelling and grammatical errors. However, I must say that the article's coverage of OOP is overly complicated.
This is not your fault but the fault of OOP as portrayed by languages like C#, Java, and C. These languages make OOP harder than it has to be. These languages base OOP on the idea of Abstract Data Types and, as such, require all sorts of weird workarounds in order to make OOP usable. This kind of OOP is a bastardization of Alan Kay's brilliant OOP conception as exemplified in the Smalltalk programming language.Smalltalk programming is a most elegant and simple way to do OOP.
By comparison, C#, Java, and C make OOP a nightmare. No wonder so many OOP developers don't know what they're doing!I recently published an article that tries to give a very simple explanation of OOP because, really, OOP should be simple:. Hi, I know I am a little late to post an answer to this question, but it might help someone though.A class is like a blueprint of the instances / objects which surround us, for eg: if have four pen objects with you, you categorize that as 'Writer', you can create a 'Writer' class which can serve as a super class and then you can create a more specialized classes like Pen, Pencil, Marker, SketchPens, ColorPens,etc.
See basically by creating a class we are practising encapsulation (one of features of OOPS). Elethelectric Penguin 11-Jan-17 9:1911-Jan-17 9:19I approached this article with a reasonably sound existing conceptual background in OOP so I can't really comment on how useful this is to an OOP foreigner, however.I found your article to be educational, insightful, entertaining and intellectually appealing. I especially enjoyed the part where you discussed the interaction of data patterns.
It gave me a new perspective on data analysis and behavior classification.Thank you for taking the time and effort to put this together. Don't let the critic's get you down, not everyone speaks English natively and in my opinion you do a pretty decent job of getting your point across.This brings me to my two questions regarding the article. Firstly, I'm attempting to launch an educational blog focused on OOP and other related conceptual theories and philosophies.
Would it be alright to cite some of your work in one of my posts? Of course I'll provide source attribution as well as link to, and recommend this article.Secondly, are you still looking for someone to edit this article? In terms of fixing it, grammatically? If so please let me know, I speak English as a first (and only) language and I'd be happy to rewrite your article for you. Oh and yes, for free haha.
I only ask that in return you acknowledge my contribution, and should you feel it appropriate, consider linking to my blog. (It's not live yet).Anyway, even if the answer to both those queries is a resounding no I still wish to express my gratitude towards you for putting in the hard work and coming up with an article of high quality, and, I personally feel, of great intellectual merit.Good luck in your future, wherever it takes you. Member 11177484 9-May-16 16:289-May-16 16:28I have been developing software professionally for two decades.
I have worked for several fortune 100 companies such as Time Warner Inc. , ESPN and JP Morgan. I am currently employed with an international commercial software company, AVG.
Articles such as these are the reason this profession is littered with:' As a number of years pass by, these developers become leads and software architects. Their titles change, but the old legacy of not understanding, of not having any architectural experience, continues, creating a vacuum of good architects.
The bottom line is that only a small percentage of developers know how to design a truly object oriented system. 'I noticed that there is a knowledge gap, increasing every day, between architects who know how to architect a system properly and others who do not. The ones who know, know it right.
But the ones who do not know, know nothing.' And seriously, the second quote here reads like a third grader wrote it.
Now let's move onto the grammar.' But how the hell is one supposed to have experience if no one is willing to give him a job? As in the general case, the start with software architecture is no exception'.'
In real world, you'll often find many individual objects all of the same kind. As an example, there may be thousands of other bicycles in existence, all of the same make and model. Each bicycle has built from the same blueprint.' .what is the author trying to explain with this statement?
This is not even a coherent statement. And why does the author refer to a 'Student' class in the previous paragraph and jump to bicycles in the next sentence????This statement is misleading and just incorrect.'
OOP is a design philosophy. It stands for Object Oriented Programming. Object-Oriented Programming (OOP) uses a different set of programming languages than old procedural programming languages (C, Pascal, etc.)'.try a google search using 'OOP with C' or 'OOP with Pascal' or 'Object Pascal' or 'Objective C'.' The Open Closed Principle -Should be able to extend any classes' behaviors, without modifying the classes.'
Does not describe the principle to the reader.very confusing.even Wikipedia does a better job describing this principle.' In object-oriented programming, the open/closed principle states software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification; that is, such an entity can allow its behavior to be extended without modifying its source code.' Now how about some contradictions.' This article is a constructive attempt to group/ define/ explain all introductory concepts of software architecture for seasoned developers who are looking to take their next step as system architects.' This article is an effort to provide an accurate information pool for new developers on the basics of software architecture, focusing on Object Oriented Programming (OOP).I could keep going, but just not worthy of my time. To sum it up, readers please, please purchase a book on the subject!
Sorry about the delayed response.I respect you for spending your quality time to criticize my article. That shows your enthusiasm to get something better. Mate, I have no regret in reading your comments.But please understand my side of the story, I got four people to review and improve this article, unfortunately they were all non-tech reviewers. As yet I couldn't find a good ENGLISH tech guy who is generous enough to help me by doing this for FREE. So this is all I can do, as English is not my native language.Are you will to take it and help me?? If you do so, I will not hesitate to share the authorship of the article with you.
This article is attracting thousands of viewers on daily basis. So definitely it is not a waste of your time.Best Regard,Nirosh. I don't deny it.But you know what, I got at least four people to review and improve it, they were all non-tech reviewers. As yet I couldn't find a ENGLISH tech guy who is generous enough to do it for me for FREE.I want you to research along this article and then you will see the number of readers it attract every day despite all the issues it is having. Here is a deal. If you are willing to review it for me, I have no regret in sharing the authorship with you. Will you take it??Best Regard,Nirosh.
