    Default How to write this without

    HashSet<String> Cats = map.getAll();
    int numCats = Cats.size()

    I have tried in so many different ways, but I always get an unchecked exception. getAll generates a HashSet.

    int numCats = map.getAll.size();
     
    HashSet<String> Cats = new HashSet <String>();
    Cats = map.getAll(); or Cats.add(map.getAll());
     
    etc

    no matter what I do I get unchecked

    I don't understand the question. If you are asking how to do it without the Generics then I counter with: Why do you want to do that?

    If you get the "unchecked exception" then it is only a warning. your code will still compile and run. Or you can compile with the "suppress warnings" option.

    If you want help with code, you'll have to post an SSCCE demonstrating what you're actually doing. Otherwise we're just guessing.
