...s using the "Map" interface restricts you to only those methods unless you cast the collection back from Map to HashMap (which COMPLETELY defeats the purpose).
Often what you will do is create an object and fill it in using it's specific type (HashMap), in some kind of "create" or "initialize" meth...
