of the answer Just a beer Incorrect because you can
- 00:27
never actually in stan she ate a new list They're
- 00:31
like abstract classes or interfaces where you can declare an
- 00:34
object is being a list but not actually fill it
- 00:37
with one so sorry list you just didn't make the
- 00:39
cut D is incorrect because there are no parentheses after
- 00:44
the array list Nit picky yes but then again so
- 00:47
is all of computer science Well that leaves us just
- 00:49
with choi si is the correct answer We can tell
- 00:52
that this follows the guidelines we mentioned earlier It creates
- 00:55
an object of type list but in stan she eights
- 00:58
with type o rh a list and doesn't forget the
- 01:01
parentheses at the end Now that we've solved this problem
- 01:04
we can check that accomplishment off both our ray list 00:01:06.406 --> [endTime] and our bucket list
