Whenever application development happens, the developer concentrates on the business logic, look and feel, and persistency to be achieved. However, along with these things, the developers also give a rigorous thought on how to manage the transactions, handle the increasing load on the site, make the application secure, and much more. If we take a closer look, these things are not the core concerns of the application, but still, these are unavoidable. Such kind of code that is not handling the business logic (functional) requirement but is important for maintenance, troubleshooting, and managing security of an application is called a nonfunctional code. In most of the Java applications, along with core concerns, the developers have to write down nonfunctional code quite frequently. This leads to providing biased concentration on business logic development.
