       I really dislike Utils classes in Java. They never age well, tend to make life very difficult to test, and spread all over the code like goo. Avoid them!(Unless you're writing a library like StringUtils - that's a different kettle of fish)#Tech #Code #Programming #Java #Architecture

       @hazz223 So where do you put functions?

       "But, i need to write this as a Utils! Where else would it go" - I've heard that a lot. Break it down. You might end up with a few more classes, but it'll be worth it in the long run - being specific and well tested. I've not written a Utils class in years. It's possible.

       @alexelcu With Java, usually small and well defined classes that attempt to do one small domain well. Makes them easy to test, highly composable, and friendly to refactor.

       @hazz223 A plain function is always much simpler to compose and test than a class. Forcing a class-based design whenever plain functions would do is what makes Java complicated.An Utils class is just a package of functions. Normally problems happen because we have a hard time with organizing things, and finding them later, but this is an issue with packages in general, and discovery could be greatly helped by conventions or tooling.

       @hazz223 I did feel some pain in our $work projects. Utils classes/packages do need some design coherence, instead of being dumping grounds for whatever doesn't fit elsewhere.
