- 00:25
without causing an error All right look intense herod act
- 00:31
all handsy there with hi aren't you done reading All
- 00:36
right here potential answers And let's just go all right
- 00:41
so let's think about what this questions asking We have
- 00:44
a bunch of slots in an array that only accept
- 00:46
objects that are a type meat animal but let's take
- 00:49
a look at the answer is into a neat animal
- 00:52
No but we can eliminate that one by one Moving
- 00:56
on you were given an object of type pterodactyl well
- 01:00
that's not a neat animal so we can cross it
- 01:03
off the list right Wrong Pterodactyl is a subclass of
- 01:07
meat anil meaning we can store it inside of a
- 01:10
neat animal object Remember we can put sub classes into
- 01:13
super class is not the other way around And finally
- 01:17
let's take a look at our last choice String obviously
- 01:20
is not a neat animal so we can cross that
- 01:24
one off lists or answer must be beat And next
- 01:26
time we'll look it done sort of crashing their cars 00:01:29.51 --> [endTime] That's a tyrannosaurus rex
