Hi all, while usage of Java 11 specific API has started to trickle into the codebase already, for example, usage of List.of to build immutable lists.
However, there is a language feature that I still haven't seen usage of, so far: "var", aka local variable type inference. A good article about is here: https://belief-driven-design.com/local-variable-type-inference-java-10-91bf1586632/ Personally, I'm so used to the type declaration that I don't mind, but for simple cases, I would not mind seeing "var" either. What would bother me, on the other hand, would be to look at code assigning the result of a method to a local variable, and not knowing what the type is, without also having to go look at the signature of such method (somewhere else). The other bit that I'm not particularly fond of is something like: var myList = new ArrayList<String>(); because myList is now an ArrayList, not a List<String>... which would imply, that autocomplete would suggest more methods that originally intended, reducing the ability to switch implementations later. The author says, as long as it's confined to local variables, it's not too bad. Indeed, but how many make the IDE generate a new method signature by a sample invocation? I do a lot, which would make the implementations trickle down there as well, if one does not pay attention. Seems to me a "use with good judgement" feature (they all are, but this one seems tricky and involves personal views on when a target type is "obvious" vs not so). Opinions?
