The following function accepts three String arguments (Strings are collections of characters, numbers, and symbols such as “Hello World” or “14.500001”), checks whether they are valid to be used as a mathematical expression and if so, returns a String result of evaluating this expression. Each class is concerned with a particular operation, such as printing the result to the console (via println()), validation logic, evaluation logic, and our primary function still coordinates the flow of data between these different things. I am an Android developer with only 5 months of experience. We are getting into quite advanced territory which you will not need to cover unless you plan on building complex multi-platform GUI applications, but I will briefly discuss the different modules present in SpaceNotes: The majority of programmers, unfortunately, do not observe separation of concerns: This is regrettably the most common way of doing things, and the general rationale for doing so is that it can actually be really difficult to achieve separation of concerns and to build modular systems.
