If you try to store your favorite List<String>, your program won’t compile. The reason is that you can’t get a Class object for List<String>. The class literal List<String>.class is a syntax error, and it’s a good thing, too. List<String> and List<Integer> share a single Class object, which is List.class. It would wreak havoc with the internals of a Favorites object if the “type literals” List<String>.class and List<Integer>.class were legal and returned the same object reference. There is no entirely satisfactory workaround for this limitation.
