Why can't a Generic type containing a Generic type be assigned to a Generic typed class of wildcard type

Question

Sorry if the title seems confusing, but some examples are in order.

Let\'s say I have some Java class with a generic type parameter:

public class Gen         


        

Answer 1

Technically, that's because List> is not a subtype of List>. In order to make it work, you could do something like

List> generic = stringy

which should work as expected (though is pretty ugly...).
