This is arguable and pure aesthetic question. Early return has been historically avoided in C and similar languages since it was possible to miss resource cleanup which is usually placed at the end of the function in case of early return. Given that Java have exceptions and try, catch, finally, there’s no need to fear … Read more
I use an extension method: using System.Linq; … public static bool In<T>(this T item, params T[] list) { return list.Contains(item); } … if (!x.In(2,3,61,71)) … You can rename it to IsElementOf if you prefer this name…
If the code needs to run even when any other code throws an exception, then the finally block is the correct solution. If it need not run in the case of an exception (i.e. it’s only necessary for “normal” returns), then using finally would be abusing the feature. Personally I’d rewrite that method in the … Read more
I think many developers do that in Presentation layer, specifically in ViewModel/Presenter/Controller (not in Activity/Fragment/View!). My approach is to put that logic in Domain layer. Why? Is it presentation logic or domain logic? Presentation logic is something you decide “mapping render model”, “format of render model”, “how to render”, “what color, what size, which text”, … Read more

My code base now makes heavy use of Inversion of Control containers. I would never revert my code to the old way because a junior developer had issues groking IoC. Instead I would take … Read more

Remember that in Python, a file is a module that you will most likely import in order to use the classes contained therein. Also remember one of the basic principles of software development “the unit of packaging is the unit of reuse”, which basically means: If classes are most likely used together, or if using … Read more
Case 1 is concise, expresses the intent clearly, and is equivalent to case 3. Case 2 is less efficient, and also less readable. Case 3 is nearly as efficient as case 1, but longer, and less readable. Using case 3 is only better to use when you have to concatenate in a loop. Otherwise, the … Read more
