I’m using Android Studio and I write this :
List<Button> buttons = new ArrayList<Button>();
I have this message :
Explicit type argument Button should be replaced by <>
I’m curious, why would it be better to use diamond instead ?
List<Button> buttons = new ArrayList<>();
I don’t agree with the duplicate at all ! I saw that answer before and it compares explicit argument to no argument at all, whereas I compare explicit argument to implicit argument !
It is less verbose, consider the following
Map<String,List<String>> map = new HashMap<String,List<String>>();
Map<String,List<String>> map = new HashMap<>();
I think you would go for the second option
