![]() ![]() But, a long list of parameters can make it difficult for someone to read and understand the code. Parameters are essential for methods to work as per specification. There can be more conventions related to naming interfaces, enums, constants as well. While we've only discussed how to name an identifier in Java, please note that there are additional best practices like camel casing, which we should observe for readability. It's hence useful to name methods using verbs: Methods: Methods in Java are always part of classes and hence generally represent an action on the state of the object created from the class.The name of the variable should describe the intent of the variable clearly: Variables: Variables in Java capture the state of the object created from a class.Hence it's meaningful to use nouns to name classes describing them sufficiently: Classes: Class in terms of object-oriented concepts is a blueprint for objects which often represent real-world objects.A well-formed name does not only help in reading the code, but it also conveys a lot about the intention of the code. Java prescribes a set of rules to adhere to when it comes to naming anything in Java. “… if you know what something does, you got a pretty good chance guessing the name of the Spring class or interface for it …” Rod Johnson, the creator of Spring, emphasizes the importance of naming conventions in Spring: Clean Coding in Javaįollowing naming conventions can go a long way in making our code readable and hence, maintainable. Hello guys, if you want to learn Java Programming and looking for the best websites to learn Java coding for free then you have come to the right place. This leads to a lower total cost of ownership for the software lifecycle. It's beneficial to start developing with these characteristics in mind compared to refactor later. These are what help us achieve the goals discussed in the previous section. This helps establish the baseline behavior of the codebase and makes it easier to change it without breaking anything. It must be intuitive and easy to test the codebase, preferably in an automated manner. Testable: Clean code, while being simple, must solve the problem at hand. ![]() Increasing complexity in a codebase makes them error-prone and difficult to read and maintain. The software design and implementation must be as simple as possible, which can help us achieve the desired outcomes. Simple: This is by far the most important and often ignored characteristic of clean code.This applies to all levels of abstraction in the codebase like method, class, package, or module. It should not do anything strictly not related to solving the given problem. Focused: A piece of code should be written to solve a specific problem.Let's go through some of these characteristics: Codebases written with clean coding principles exhibit several characteristics that set them apart. ![]()
