Using sequential implementations and interfaces with Generics

As we have just seen, the best practice for creating a List will be this:

List<String> moreStuff = new ArrayList<>();

Any valid class type can be used. Once we have elements in our collection, we can access them with the get method and the subscript:

        String orange1 = "Valencia";
