Thank you We sneak and here's your shmoop du jour

00:05

featuring a raise who won't be happy until their array

00:09

lis it's Sad to see them so listless But which

00:15

of the following is a correct initialize er of an

00:17

array list of strings All right let's go through each

00:24

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
