design - Controller want to know if list's View is empty -

-

admit have 2 class : view , controller, knows each other.
view has object list named list , controller want know if list empty or not.

what best way ?

if that's interaction between list , controller, implement boolean islistempty() method in view class in define logic determine whether list empty. way, don't have expose type of list controller , keep program flow in controller simple if view.islistempty() something.
