Hello, I have a doubt about generics usage with the iterator
interface.
The following declarations should be 'equivalent', I mean, all the
methods return the same type (a reference to Object):

Iterator it;
Iterator<Object> it;

Well, now consider the following code:

Vector<Animal> v;
...
Iterator<Object> it = v.iterator();

It doesn't work, since v.iterator() returns a Iterator<Animal>
reference, which is incompatible with Iterator<Object>,
but:

Vector<Animal> v;
...
Iterator it = v.iterator();

It works fine, but v.iterator() returns an Iterator<Animal> reference,
why are both references compatible??

TIA
