I have a set of Strings (it's static) and I would like to create a Map<String, List<String>> from them, where the list is initialized to a new ArrayList. Something like the following, but this code is not correct.
static Set<String> MY_TYPES = Set.of("type1", "type2", "type3");
Map<String, List<String> myMap = MY_TYPES.stream().map(t->() t, new ArrayList<>()).collect(Collectors.toMap());
I am trying to learn how to use streams better in my code. I know I can do this iterating over the Set.
Edit
@shmosel, you are correct. I want the equivalent of
Map.of("type1", new ArrayList<>(), "type2", new ArrayList<>(), "type3", new ArrayList());
