We should acknowledge this truth, but not use it as a reason to actively fight every reusability flaw until we really need it — good software design rules still apply. See the original article here. Real life examples are STL, Boost, QT, and “you name it” library. Document it and unit test it and make it open source. Understanding meaningful example of Aggregation Obviously, it won't be any close to complete, rather an inspiration to explore further. By Hemant kumawat - May 19, 2016. Is Java “pass-by-reference” or “pass-by-value”? If I want to make this app reusable for many other applications as a component of other applications. The biggest advantage of inheritance is code reusability, since the fields and methods of parent class get's inherited in child class, the child class won't have to create it again. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. We can achieve 100% abstraction using interfaces. Java/A integrates notions like components and connectors into Java. Reusability is what its name suggests - reusability. I believe it's not (yet) mathematically proven, but a component's reusability is inversely proportional to the amount of magic it uses and dependencies it requires. Reusability implies some explicit management of build, packaging, distribution, installation, configuration, deployment, maintenance and upgrade issues. Reusability is achieved by INHERITANCE .

It can access those features from parent class, that is what the code reusability is. How do I convert a String to an int in Java? Since poor dependency management and magic seem to be ubiquitous in software, reusability tends to suffer. It gets crazier from there on out. Reusability brings several aspects to software development that do not need to be considered when reusability is not required. Now, for some of you, this will be valid, whereas some may say that I'm actually defining a module, and some of you might want to nitpick other details in the definition. Polymorphism is implemented through operator overloading and function overloading. Poly = many and morph = forms That means the same data members can be represented in many forms and it also opens the door for providing overriding concept which again helps through reusability . Java Beans are, quite simply, reusable controls written in Java, for Java application development. You can find a lot of definitions and approaches to defining a component. You should observer the following: You have a couple of options for the mechanics of packaging: This is a rather broad question. What can we say about this component's reusability?

GO AND REWRITE, HAHAHA! Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. -Information hiding is achieved by restricting access to class members via keyword public. Abstraction can be achieved by Composition. Java does not have multiple inheritance, but its designers claim that many of the benefits of multiple inheritance can be gained through the use of a new feature, the interface. By doing this, we are reusing the fields and methods of the existing class. Ubuntu 20.04: Why does turning off "wi-fi can be turned off to save power" turn my wi-fi off? So what is the Polymorphism?

As such, I am offering broad suggestions: You need code in such a way that your components are loosely coupled. The meaning of 'extends' is to increase functionality. If inheritance is not used, multiple classes may need to write similar functions/logic in their body.

Reusability: As the name specifies, reusability is a mechanism which facilitates you to reuse the fields and methods of the existing class when you create a new class. You can use the same fields and methods already defined in the previous class. Code reuse is also best achieved by aggregation when there is no is-a relationship. It is basically achieved by combining an existing system of any language (.Net or Java) with the other language to give you a new product without changing your existing systems. Grow your knowledge in clean environments. A component should be well encapsulated to encourage loose coupling. This is going to be a bit long answer since this is a vast topic and I will also point out the difference of using Reusability during software and hardware coding.
