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

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
