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). Perhaps the greatest promise of using object-oriented paradigm is the code reuse. b) Object must be used is violated They make it possible to reuse code without creating security risks or making a Java program less readable. Services There is a lot of research, and this shows it can be done in many circumstances. What Design Patterns for encouraging component reuse? a) Classes must be used better. That's a question of its architecture whether it stores state internally or, like Smalltalk's Integer classes, instantiates new objects with new state. Interfaces and contracts are the core to code reuse in OOP systems. The chair analogy is nice and all that but just one word: Lego. 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. Code reuse takes a willingness to not repeat code, an understanding of how to accomplish it, upfront planning. View Answer, 3. That has achieved for us at least some of the promise of (knowledge) reuse: extremely significant productivity gains. A simple and seemingly harmless example is those classic diagrams where you inherit from a parent … KEYWORDS: Object Oriented programming Language, Inheritance, Software reuse and maintainability. Researchers studied ways to maintain software quality and developed object-oriented programming in part to address common problems by strongly emphasizing discrete, reusable units of programming logic[citation needed]. services. c) Message Passing How to use a protractor if you can't see what you are measuring? b) Polymorphism happen. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle. b) The language should follow at least 1 feature of OOP There really is no such thing as "reuse" the way that people describe it. How much do you have to respect checklist order? One of the most compelling features about Java is code reuse. At first I thought the whole concept didn't make sense. Then, my thesis supervisor said "But you're wrong, Erlang is extremely object oriented". You can give 30 votes per day, don't waste them. - The inheritance feature allows us to define a new class by extending or modifying an existing class. c) Abstraction The basic types of code re-use within applications made it possible to write applications that did more, and to write them faster.). orchestration services. The OOPs allow reusing of code using inheritance where child class can inherit all the properties of base (Parent) class. That identifies your code and can describe the process too. Would you have hundreds of methods in a List-class? - 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). Injecting the right instances into classes or passing them as parameters is the hardest part of OOP. Which among the following, for a pure OOP language, is true? Summary: reuse of generation knowledge is the win, not reuse of code. 6: Reusing Classes. Code reuse may imply the creation of a separately maintained version of the reusable assets. And of course it's hard to reuse. a) 7 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. b) Inheritance b) Inheritance Most object-oriented languages implement a concept of visibility. 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. Making statements based on opinion; back them up with references or personal experience. I would post a long answer but why? a) True 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.
