reusability meaning in java

Advantage of Methods in Java. Similarly in Java, we can have functions or methods that describe a specific code behavior. Loose coupling : In simple words, loose coupling means they are mostly independent.If the only knowledge that class A has about class B, is what class B has exposed through its interface, then class A and class B are said to be loosely coupled. We should always write methods only within a class. This prevents us from writing redundant code and enhances reusability. Reusability In programming, reusable code is the use of similar code in multiple functions. Reusability in Java means that once you write some code, you can use it over and over again - if you write it so that it can be reused. But to be revolutionary, you’ve got to be able to do a lot more than copy code and change it. In OOP, The concept of inheritance provide the idea of reusability. Introduction to Generics in Java. The new class will have the combined features of both the classes. Aggregation in Java. That’s the approach used in procedural languages like C, and it hasn’t worked very well. Note: The biggest advantage of Inheritance is that the code that is already present in base class need not … Like everything in Java, the solution revolves around the class. Aggregation represents HAS-A relationship. If a class have an entity reference, it is known as Aggregation. This is possible by deriving a new class from the existing one. One of the most compelling features about Java is code reuse. Java Inheritance (Subclass and Superclass) In Java, it is possible to inherit attributes and methods from one class to another. Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. Reusability: Methods allow us to reuse the code by just calling the specific function. Inheritance allows us to reuse of code, it improves reusability in your java application. Consider a situation, Employee object contains many informations such as id, name, emailId etc. No, not by copying and then pasting the same code from one block to another and from there to another and so on. Our client, an enterprise software company and one of the leaders in travel domain, was maintaining 5 websites. Generics in Java arethe advanced feature that helps to achieve code reusability and type safety. This means that we can add additional features to an existing class without modifying it. ... - It is useful for code reusability: reuse attributes and methods of an existing class when you create a new class. Let's explore this in detail. This brings us to the end of this article where we have learned about Association in Java. The code reusability functionality in java is managed by defining generic classes, interfaces, constructors, methods. As a live example, we recently explored Component Reusability for a client partner to bring in cost and time savings.
