To practice all areas of Object Oriented Programming (OOPs), here is complete set of 1000+ Multiple Choice Questions and Answers. Horizontal Reuse: aspects, traits, grafts. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. component-orientation was the thing What most people mean when they talk about "reuse" is "use". FP might be better for code reuse, but imho not for easily reusing the kind of code that people actually need to write nowadays. But getting the abstractions right to write sane functional code while meeting a deadline may not be doable. Not a very comfortable bed, but I can do that. The most beautiful part of it, that it can done visually, because there're no parameters or orher tweaks on connections, they really just connects a consumer and a producer. The technology focuses on data rather than processes, with programs composed of self-sufficient modules ("classes"), each instance of which ("objects") contains all the information needed to manipulate its own data structure ("members"). Been pretty well distracted by applying program transformations not so much to abstract specifications to generate code, but rather to legacy code to clean it up. I will not reuse the plane. Another way to reuse code in OOP is using tools like inheritance, interfaces, polymorphism, traits, etc… the others already mentioned. c) Polymorphism There's too many ways to reuse. If you can vote and think this is a useful question or it have useful answers below, please vote up. Why do exploration spacecraft like Voyager 1 and 2 go through the asteroid belt, and not over or below it? A domain specific component, which allows non-domain experts to do their job with less knowledge about the domain is a (re-)useful component. 6. b) Polymorphism Making statements based on opinion; back them up with references or personal experience. OOP concepts allow us to create specific interactions between Java objects. dirty-little secret: I agree with Chris, functional programming is a good way to reuse code. the reuser needs to somehow specify what he needs (functionaly, performance, target language, environment assumptions, ...), there must be a library of "reusable" code that has been indexed in various ways by these potential criteria, some mechanism must exist to pick out candidate elements (at a billion elements, you can't look at them all personally), there needs to be a way to characterizer how far away from the specification the chosen candidates are. That's not to say that lots of utility libraries and snippets of code couldn't have done the job as well, but there's something pleasing about a well designed object hierarchy. Wich makes easier to maintain it. d) It’s vice-versa is true There is a lot of research, and this shows it can be done in many circumstances. @Matthieu M.: Indeed, generics reduce code replication, so it's "more reusable", yes. Perhaps the greatest promise of using object-oriented paradigm is the code reuse. d) Message reading Like everything else, I'll figure it out. For example, when a developer extends it, refactors it, or debugs it, they can easily find out the inner coding structure and maintain the code time after time. To save development time, code reuse is often seen as a method of cutting project costs and shortening time to market, but it has several benefits of saving time.This study provides an arguably much needed real, industrially-based experiment regarding brainstorming. What ways are better? If you make the code chunks huge, they're pretty much useless in a new context. There are 3 basic features of object oriented programming language: Inheritance Polymorphism Encapsulation Could you please explain polymorphism with code. OOP is a gray box attempt in creating a component technology. Datadlow paradigm provides a strict interface for components, they have ports of following types: Depends on the domain, there're some packet types, so consumers and producers can be connected it they have same (or compatible) ports. In general objects are for encapsulation and not for code reuse, code reuse requires something more and the class inheritance hierarchy is a poor substitute for what a code reuse mechanism should really be. c) Operator overloading All Rights Reserved. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. OOP also promotes interface reuse and design reuse. I wish I had your luck because I have seen code reuse in the non-generic form. View Answer, 8. At best they provide an environment conducive to implementing it. Which feature in OOP is used to allocate additional function to a predefined operator in any language? c) Operator Overriding Inheritance is the real payoff of OOP. From a functional programming view OOP is mostly about managing state. View Answer, 4. I will just use it for the purpose it was intended for, there's nothing fancy or exciting about that. I consider AOP as the missing half-orange of OOP. Thus, your projects shorten and get more readable. If we can do this, then we can apply that knowledge to construct code that we need, handling the current set of assumptions. reusing, and creating reusable For more on this see the first chapter in Real World Functional Programming. ...gave me (the) strength and inspiration to. Actually, OOP seems to have a level of abstraction cup, when the alternatives are not limited at all. I think that deep inheritance in OOP can be misleading in many cases. December 2, 2020 / 0 Comments / in Uncategorized / by / 0 Comments / in Uncategorized / by I call that "FP using classes as namespaces". programmers.stackexchange.com/questions/1059, meta.programmers.stackexchange.com/questions/393/…, programmers.stackexchange.com/questions/1059/…, practical program transformation systems, a tool called DMS. Do the axes of rotation of most stars in the Milky Way align reasonably closely with the axis of galactic rotation? For example, we may create a piece of code that calls specific data from a database. Typically the existing class is called the parent class, and the derived or extended class is called the child class. Users need to understand the interface, less so the intricacies of the problem domain. a) Inheritance can’t be implemented @Steven A. Lowe Well I wish that were true. The object-oriented programming approach allows developers to bind and manipulate data using exclusive functions.These functions cover a range of operations, including code reuse and variable designation. They make it possible to reuse code without creating security risks or making a Java program less readable. 1. It's probably not better or works, but provides another tool in the toolbox. Like everything in Java, the solution revolves around the class. View Answer, 9. 6: Reusing Classes. c) It depends on type of program © 2011-2020 Sanfoundry. Formalized specification languages, standardized test notations (e.g. But to be revolutionary, you’ve got to be able to do a lot more than copy code and change it. This feature allows us to reuse code we've written and extend it. The difference between domain specific and generic "frameworks" as subject of re-use deem me too abstract. That’s the approach used in procedural languages like C, and it hasn’t worked very well. For example, let's say we want to be able to define a math student, which also knows how to sum two numbers. I started investigating "code reuse" as a research topic back in the 80s, after discovering I had reused the design of one OS I built in the early 70s, for another OS I built in the late 70s. c) Inline function That's a question of its architecture whether it stores state internally or, like Smalltalk's Integer classes, instantiates new objects with new state. -1. Yeah, the resulting knowledge behind the code would be much clearer after the OO to FP rewrite maybe... but the cost could be huge and it might be the kind of cost that would also have to be payed by people wishing to reuse the incredibly smart and well abstracted code you end up with, so paradoxically, people would end up not reusing the code, even if technically it's more reusable. I thought the question was about code reuse, not nice semantics..? Rather than explaining them, there is a great PHP RFC that explains both. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. How much theoretical knowledge does playing the Berlin Defense require? some regular process should exist to allow the reuser to modify the chosen reusable code Was it a good thing? services. b) Function Overloading What are the features required for Object Orientation? were Joe Armstrong is quoted: I started wondering about what object oriented programming was and I thought Erlang wasn't object oriented, it was a functional programming language. But it is a big time saver often to stick to a specific architecture to tackle a new, similar product. d) Virtual Function happen. In CommonLisp there are lots of means to achieve reuse: dynamic typing, having your code be generic by default, imperative abstractions, i.e. With these tools, each line of code does more. OOP gives you more ways to reuse code. Do Magic Tattoos exist in past editions of D&D? Your classes must inherent their components in order to use the. Why are inheritance and polymorphism so widely used? I think the biggest benefit of OOP is the general acceptance of how code should be organized. View Answer. Entire books of patterns have been b) The language should follow at least 1 feature of OOP Apparently that didn’t pan out c) Encapsulation only is violated The good part of code reuse is the ability to sometimes reuse honest-to-god preexisting code. d) Function Overriding Then applications would just be a little glue here and there. You can read several books in the topic, but probably Clean Code is the most famous amongst them. d) Basically all the features of OOP gets violated I am not sure OOP is simply there to provide code reuse. Asynchronous message passing as in event driven systems and in Erlang is also a very good way to decouple systems and loose coupling is important in complex systems. c) Message Passing Some even go so far as saying that the Or with more quality? Like Gulliver, they are tied to the beach by a million tiny strings, and you simply can't afford to cut them all. What Design Patterns for encouraging component reuse? There are many wrong ideas about Object-Oriented Programming. Classic OO sometimes falls short on code reuse, specially when you go all inheritance crazy for lack of a better way to share actual functionality between classes. c) Abstraction Which feature of OOP indicates code reusability? Code reuse is a pretty good idea. That identifies your code and can describe the process too. Or easier to maintain? Udi Dahan explains it much better than I can. However, the Sweeper tool using internally s… In my opinion, the main features of OOP are: Good representation of reallity through the modelling of classes. Levels of re-use often forgotten: Idea re-use, Specification re-use, Architecture/Design re-use, Interface re-use, Test-case re-use. C++ gives you all the tools you need to reuse methods instead of repeating the code. Structurally, interfaces are reference C# objects with no class member implementation. Which among doesn’t illustrates polymorphism? The parameter sets have to differ in at least one of the following three criteria: (There was a crazy idea for a whole extra level of object oriented re-use: The idea was that we could define a single Customer class and use it in every application we wrote. Maybe it is not fair: 20 years of C/C++/C# experience and 6 months functional programming (F#). map and foldr that is the foundation for Google's MapReduce. a) Encapsulation Watch this two talks if you want to understand AOP better: Traits are another construct for defining reusable code that complement OOP, they are similar to mixins, but cleaner. d) Virtual function services and activity services, The object-oriented paradigm allows us to organise software as a collection of objects that consist of both data and Traits are coming to PHP btw, they are already commited to trunk. In that sense, reuse in the real world is about re-purposing things. This industry is pre-occupied with Which feature of OOP is indicated by the following code? Here's what I call the Reuse Curse: I'm Santa Claus (ok Open Source), and I have a bag of 1 billion software components. That has achieved for us at least some of the promise of (knowledge) reuse: extremely significant productivity gains. Many programs has code structures that is recurring. c) Message passing all this must clearly be cheaper than simply recoding it. Fine tuning details in C++ function for different customers. c) 5 Then, my thesis supervisor said "But you're wrong, Erlang is extremely object oriented". The humble unix pipe has done more for code reuse than anything else that has come and gone. View Answer, 14. a) Inheritance The OOPs allow reusing of code using inheritance where child class can inherit all the properties of base (Parent) class. Reusing code wasn't about re-purposing it for some functionality other than that for which it was. orchestration services. [...] Tomorrow, I will fly back to the UK. Thanks for contributing an answer to Software Engineering Stack Exchange! However, I think the real key to reusability is to define simple, small, sane, pure functions (this is the "functional programming" direction), and pass them around, which is possible in C. It's more about the general programming style than about the capabilities of the language itself. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. I have a team of about 7 technical people; we've written probably 1-2 MSLOC of "specifications" for DMS, but have some 10MSLOC of generated code. b) Inheritance Exception handling is a feature of OOP. Anytime you take a block of code and make it callable by the rest of your code such that you can use this functionality elsewhere is code re-use. KEYWORDS: Object Oriented programming Language, Inheritance, Software reuse and maintainability. Object-oriented programming (OOP) is a fundamental programming paradigm used by nearly every developer at some point in their career. They do nothing but define their properties and methods. They're more complementary than alternative: without one of them you're forced to reimplement the missing features in a clumsy way. Functional programming is very hot right now among the hipsters. In my experience, I've had more success leveraging "reusable" code through generic programming facilities (like C++ templates) than I've had using OOP principles like inheritance hierarchies. OOP doesn't provide any other help). Also many frameworks make use of inheritance to provide code reuse (Delphi, Java, .Net are just some that spring instantly to mind). How many basic features of OOP are required for a programming language to be purely OOP? But DMS has the two key properties I described above: the ability to process arbitrary formal specifications, and the ability to capture "code generation knowledge" as transforms, and apply them on demand. I don't have that luxury and refuse to scrap my career over some ivory tower theory. I do not agree. If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? What will be the proper answer, if it is asked in interview. Mostly what has been discovered over the years is that for code to be reusable, it sort of has to be designed for that purpose, or it contains too many implicit assumptions. Object-Oriented languages allow … Join our social networks below and stay updated with latest contests, videos, internships and jobs! But people don't look at the source code in the libraries; they simply call a well-documented API (designed to be generally usable). - The original class is called the base class (or super class) and the new class obtained through inheritance is called as the derived class (or sub class). I am sorry that i have not expressed myself in a way that has prevented this misunderstanding: what i meant is that the difference between OOP and FP is not that OOP ecourages code reuse more than FP does (what the headline implies). And of course it's hard to reuse. Is there a difference between Cmaj♭7 and Cdominant7 chords? Each public class asks: "make a new instance of me! Specification, Design, Implementation are coupled, yet not easily traversable views on the "same thing". At first I thought the whole concept didn't make sense. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. b) Data Binding Agreed, the cost of making code reusable is really high, so it does not pay off unless you're talking on the scale of the Java or .NET base classes. Object Oriented Programming: The Wrong Path? Interfaces and contracts are the core to code reuse in OOP systems. See more about this in We will learn about these concepts later. I'm trying to build practical program transformation systems, a tool called DMS. Much more vital for increased future productivity than a new programming paradigm is, to close the gap, to increase (automated reasoning, traceability) the mutual benefits between those views. pinning our reuseful hopes on Starting a code file with a class statement followed by many unrelated, perhaps even static functions, is not so uncommon. have been classified every which way But the same code, containing the same knowledge, would be even harder to reuse without OOP. Unibet made a great presentation about this: Domain Event Driven Architecture. c) Inheritance and polymorphism Participate in the Sanfoundry Certification contest to get free Certificate of Merit. I might as well let you in on the Which feature in OOP allows reusing code? In my POV it's about imperative state management. There are claims that it is better to learn it from the beginning which avoids having to rewire your thinking when it comes to programming. Is there a service for efficiently solving redundant software problems. Tell us your experience with OOP reuse or other paradigms reuse. Why? The object-oriented language uses an object-oriented programming technique that binds related data and functions into an object and encourages reuse of these objects within the same and other programs. d) Abstraction I can reuse these seats here and rearrange them to form... a bed! What is the importance of probabilistic machine learning? I think the key flaw is that any kind of code reuse is fundamentally limited because code has too many assumptions built in. You can have any one of them. b) False OOP Provides a set of useful tools that allow you to write code that can be used in more places than you could have without those tools. And no language is so strictly OO that it will throw an error when it thinks you should have inherited code from another class. AOP is not really that known, but it has made it to production code. - and all these ways of reuse are different, they have different parameters, they appears in different context, all have their different rules, how to call/extend/override it. (B) class. I am very curious what the post-functional future brings and hope to see it before I retire ;). whole point of object-orientation was View Answer, 3. And rewriting it to be functional style might need totally changing the way you think about that code, the knowledge behind it. b) Inheritance ), which may have hidden side-effects I cannot even see (lazy evaluation, monads,...). a) True a) Data transfer Don't get me wrong, functional programming has very cool sides, but all the strengths proclaimed I see with a good measure of doubt. ...which leads to the last subtlety: code reuse is about the People|Code interface, not about the code only. Can you identify this restaurant at this address in 2011? Polymorphism. But the world is full of code; how can find what you want? INTRODUCTION . a) Classes must be used StackExchange sites need votes to build a good community. But that ain't OO ;). Function calls Function calls are another way of reusing the code from various parts of your application. through process services and In compiling the following list I picked out those descriptions which are not actually unique to OOP as those features which already exist in non-OO languages cannot be used to differentiate between the two. This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on “OOP Features”. It doesn't come to me automatically. As Joe Armstrong said about OOP: The problem with object-oriented languages is they’ve got all this implicit environment that they carry around with them. Not a very good attempt; pretty much what one says in most UML models is "I have data that looks like this". While code is the most common resource selected for reuse, other assets generated during the development cycle may offer opportunities for reuse: software components, test suites, designs, documentation, and so on. ttcn3) and programming languages supporting verification of interfaces and contracts against specifications without comment-littering might be what we need most urgently. a) Operator Overloading I would post a long answer but why? "And no language is so strictly OO that it will throw an error when it thinks you should have inherited code from another class" - not yet, anyways! written on how to achieve reuse with People will believe anything they see in print. As usual we start with a simple example: SpecialAccountTest.java This is in contrast to the existing modular programming that had been dominant for many years that focused on the function of a module, rather than specifically the data, but equally provided for code reuse, and self-sufficient reusable units of programming logic, enabling collaboration through the use of linked modules (subroutines). View Answer, 11. When you use a library, you are using it for what it was intended for, normally. Explanation: Inheritance indicates the code reusability. reuse – it wasn’t, encapsulation was and metaprogramming. d) The language must follow all the rules of OOP 2. An example would be an aspect that tells "for all methods of certain classes that start with get, you program will write to a log file the data that was got and the time it was get". View Answer. Public methods are considered an interface to the internal state which you want to keep small. With a sufficiently decoupled system you can evolve the system while it is running, maybe on different nodes. Not a great one. It provides you with a whole separate set of tools to make each line of code do more. Asynchronous message passing is also a good way to organize complex software, and some computer scientists state that objects was assumed to communicate with eachother asynchronous as in the Tell, don't ask OOP principle. rev 2020.12.8.38145, The best answers are voted up and rise to the top, Software Engineering Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. d) Encapsulation and Inheritance You have a class and many of the closely related methods are implemented in different files. Arguably libraries and frameworks are "reusable" code and they are extremely successful; Java and C# succeed not because they are pretty good computer languages, but rather because they have huge well-designed, implemented and documented libraries available. d) Data hiding A team of programmers may not fully agree on how all the classes should be structured, but they should be able to find the code. Another OOP principle for reuse and efficiency is polymorphism that favors the use of a common interface instead of concrete implementation. P.S. Does OOP fulfill the promise of code reuse? c) Data may/may not be declared using object As a community, we aren't very good at this yet. the orientation of the day. Which feature may be violated if we don’t use classes in a program? Code reuse takes a willingness to not repeat code, an understanding of how to accomplish it, upfront planning. b) 6 (To build such tools takes a lot of time; I've been doing this for 15 years and in the mean time you have to eat). If you try to compare the CommonLisp experience to other languages you'll see that the major feature that eases code reuse is the presence of both object-oriented and functional abstractions. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle. Pretty hard to generate a real program if the functionality is left out. What alternatives are there to achieve code reuse? a) Always true for any programming language so well either because here we are now the big thing. In my view on things, a component (a concise, minimal and re-usable interface contract and the implementation behind) can only be done, if the problem it addresses is well understood. US passport protections and immunity when crossing borders. View Answer, 2. (C) inheritance. Exception Handling & Static Class Members, Assigning Object, Passing & Returning Object, Default Arguments, Upcasting & Downcasting, here is complete set of 1000+ Multiple Choice Questions and Answers, Prev - Object Oriented Programming Questions and Answers – Objects, Next - Object Oriented Programming Questions and Answers – Polymorphism, Object Oriented Programming Questions and Answers – Objects, Object Oriented Programming Questions and Answers – Polymorphism, Java Programming Examples on Mathematical Functions, C Programming Examples on Bitwise Operations, Java Programming Examples on Exception Handling, PHP Questions & Answers – Basics of Object-Oriented PHP- 1. As a first step I shall debunk some of the answers that I have seen. Services They help write an application with OOP elements, yet I would not see them as a solution to the "code re-use" question beyond a single application. The ability to reuse existing objects is considered a major advantage of object technology. However I think that most of the code reuse is done by using libraries and frameworks. Mr. Dahan is preoccupied with strawmen; no one seriously reuses non-generic code as he implies, and if you remove that argument from his article, he is in fact in favor or reusing code. You create small code blocks of an algorithm or logic-based source code and provide it a name, identifier. How to find already existing code | How to arrange code in a way it can be found again. It gives me much less ways of writing a generic, reusable, highly abstract code than the other paradigms, such as functional programming (mind currying, combinator libraries, etc.) in trying to achieve this, from entity Like with most other components of OOP, C# interfaces are often better understood in term… Object Oriented Programming: The Wrong Path? I know, this is crazy talk. d) Encapsulation a) Inheritance It wasn't pretty. Probably we all agree that code reuse is a good thing, but there are several ways to achieve this goal. For me, yes, but not all the time, and it could have been done other ways. b) Function overriding In which programming paradigm can't code reuse be (easily) achieved? a) Platform independent c) Abstraction View Answer, 7. This will change as the kind of code that we need to write changes. It prevents less cases of duplicating code and allows code to change at any time. OOP does a decent job of serving this interface because it maps well with how many people think about many kinds of code written nowadays. The feature by which one object can interact with another object is _____________ Are there better methods to achieved code reuse than object orientation, sub-classing, polymorphism, etc.? Also, functional programming may results in more reusable code. That is called method overloading and represents a static form of polymorphism. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Pure functions are particularly reusable: for example, java.lang.math.sqrt(double) takes a number in and gives a number out. - The inheritance feature allows us to define a new class by extending or modifying an existing class. I'll try it to explain in simple terms: imagine that you can inject and filter functionality with a special structure called an aspect, these aspects have "methods" that define what and how is going to be affected through reflection, but at compile time, this process is called weaving. A simple and seemingly harmless example is those classic diagrams where you inherit from a parent … After that subroutines, object-orientation, with multiple inheritance and multiple dispatch, syntax-abstraction, the ability to define new syntactic constructs or abbreviate boiler-plate code, functional abstractions, closures and high-order-functions. It’s a powerful OOP concept in Java because it helps us save a lot of time. b) Data binding Most of my experience involves relational databases, so I think in tables and joins. reuse. Maintenance: Object oriented code is easier to maintain because it follows somewhat strict coding conventions and is written in a self explanatory format.
