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

00:05

brought to you by snails that fly pretty soon it'll

00:08

be pigs and then everyone will be in trouble Fuck

00:14

all right Which of the following code segments will not

00:16

cause an error And i think it's going All right

00:22

let's go through Each of our choice is to try

00:24

to eliminate some choice is wrong because a no pointer

00:28

exception will be thrown Rockets nail hasn't been initialized when

00:32

they called my height is made Remember any time in

00:34

job that there is a dot after no object in

00:37

error will occur Choice b runs into the same air

00:40

it hasn't been initialized when i called to the constructor

00:42

occurs and choice see is incorrect because we haven't defined

00:46

a class called rockets nail It doesn't exist well he

00:50

looks like it could work no no pointer exception and

00:53

all the glasses air really so let's come back to

00:56

this one Our last choices in correcting his forced of

00:58

lives and interface not a class you can't in stan

01:01

she ate new interface so that leaves are correct answer

01:04

as d Next time we'll look at the snail who

01:07

joined the mlb he had to remove his shell so 00:01:10.388 --> [endTime] he could be a slugger
