Inheritance allows the user to reuse the code whenever possible and reduce its redundancy. Encapsulation lets us re-use functionality without jeopardizing security. Code reuse through inheritance. b) False All Rights Reserved. They do nothing but define their properties and methods. 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. Code re-use is achieved in OOP but it is also achieved in functional programming. (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. Specially users with high reputation and low counting votes given please read this: IMHO, The best answer. Why? © 2011-2020 Sanfoundry. The process of showing only necessary features of an object to the outside world and hide the other irrelevant information. It wasn't pretty. If you have only immutable classes, you're emulating FP, why do OOP in the first place? OBJECT-ORIENTED PROGRAMMING OBJECT-ORIENTED PROGRAMMING PROMOTES MODULARITY AND REUSE It is often “claimed” that object-oriented programming is a better way of writing more modular programs leverages code sharing and design reuse minimises maintenance costs Thanks to its abstraction mechanisms 10 11. Participate in the Sanfoundry Certification contest to get free Certificate of Merit. View Answer, 14. OOP is a gray box attempt in creating a component technology. 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. It prevents less cases of duplicating code and allows code to change at any time. so well either because here we are now So OOP in itself is not bad from pov of making reusable code, but the kinds of code that get written using OOP are inherently hard to reuse. Why are inheritance and polymorphism so widely used? 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. Which of the following is not a feature of pure OOP? In OOP, polymorphism refers to the ability of a variable, function or object to take on multiple forms and have multiple behaviors. To practice all areas of Object Oriented Programming (OOPs), here is complete set of 1000+ Multiple Choice Questions and Answers. What ways are better? whole point of object-orientation was UML models with code generation are one attempt to do this. orchestration services. a) Inheritance can’t be implemented This set of Object Oriented Programming (OOPs) Multiple Choice Questions & Answers (MCQs) focuses on “OOP Features”. 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. Wich makes easier to maintain it. FP might be better for code reuse, but imho not for easily reusing the kind of code that people actually need to write nowadays. Users need to understand the interface, less so the intricacies of the problem domain. And no language is so strictly OO that it will throw an error when it thinks you should have inherited code from another class. Tell us your experience with OOP reuse or other paradigms reuse.
