Two of the legal Narrowing Reference Conversions in Java are:

(i) A conversion from an interface S to a class T if T is not a final class.
(ii) A conversion from an interface S to a class T if T is a final class and
it implements S.

Explain these rules giving an example of each.  Be sure to address why the
"final" part (i.e., "T is not a final class" in rule (i) and "T is a final
class" in rule (ii)) in these two rules is important.
