The old class is referred to as the base class and the new one is called the derived class or subclass. 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. Show activity on this post. Yes, we cant write any code in methods of interface. If there were more repositories to track, we would need to change both service's and component's implementation. The reusability of code is achieved with overloading since the same method is used for different functionality. Code reuse is also best achieved by aggregation when there is no is-a relationship. So how to make it possible for other apps to use this feature of my app without changing my original code. 1.

Mail and MailSender on the other hand seem to complement each other — every new piece of information Mail class will hold, MailSender will have to reflect in the actual email sent. Furthermore, Java/A provides mechanisms to verify component configurations. The second approach to Reusability can be achieved through the combined approach of inheritance and virtual function which leads to the concept of polymorphism. Here class XYZ is child class and class ABC is parent class. How do I read / convert an InputStream into a String in Java? You can find a lot of definitions and approaches to defining a component. Inheritance. 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. Having identified two classes that are more cohesive to each other than to the rest, we should put them together — we want component structure to be explicit, not hidden in the forest of other things, not imaginary in the mind of an architect. How to dry out a soaked water heater (and restore a novice plumber's dignity)? Extending an existing class is nothing but reusing properties of the existing classes. You can find a lot of definitions and approaches to defining a component. If inheritance is not used, multiple classes may need to write similar functions/logic in their body.
