Here's how to name classes, methods, variables, and packages in Java: It's simple, and every Java developer should understand it. For Java, for example, there is the JavaBeans naming convention. Ctr could be an acronym for contract, control, customer-it could mean so many things!Īlso, use your programming language naming conventions. So, instead of using the acronym Ctr, write Customer. When I see an acronym in an unfamiliar codebase, I usually don't know what it means. Simple and descriptive code names are much preferred to mysterious acronyms. ![]() For example, explain the business operations in the API, parameters, return objects, and so on. Only document the code that is valuable in your API. At the same time, overusing documentation in code doesn't bring much value. So, documenting your API is very important. The new developers will probably create another API method, duplicating the existing one. ![]() If the API is not well documented, code repetition is more likely. As a result, other teams that don't know much about your project must be able to read your API documentation and understand it. When creating services and exposing them as an API, you need to document the API so that it is easy for a new developer to understand and use.ĪPIs are very commonly used with the microservices architecture. If there is no team agreement, there is no way the code will be written to a healthy and reusable standard. Once you agree on the rules for your code, you can hold the whole team accountable for reviewing it and ensuring the code is well-written and reusable. Code layers (controller, service, repository, domain, etc.).Code guidelines determine the rules for your code: Once you have the standards and code design, it's time to define the guidelines for your code. You will also want to determine a basic code design for the problems you want the software to solve. Meaningless discussions about code implementation will also often happen if there is no alignment with the team. Otherwise, the code will get messy very quickly. The first step to writing reusable code is to define code standards with your team. Follow standard code naming conventions. ![]() 8 guidelines for writing reusable Java code
