Interestingly, Java has both styles. You can do for (var i : list) {...} or list.forEach(i -> ...); Except for cases with local variables, I have absolutely no idea which I should prefer. Kotlin makes a cute case for the functional style with it's lambda shorthand: list.forEach { ... } I've found the functional style helpful for times I want almost add a language feature to avoid boilerplate. The functional style was added without special-purpose language changes, but the iterator version required Java to add Collections, Iterators, and eventually fancy for-each syntactic sugar.
