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

00:05

brought to you by an angry snail What the shell

00:08

is he screaming about What'll be printed when the following

00:16

code is run animal and and here your potential injuries

00:26

All right here we go We know that george our

00:28

rockets nail is flying as we call the fly methadone

00:33

Whatever We never called the fly method on henry the

00:35

orville copter So he's not flying So when the code

00:38

prints out whether the two are flying or not you

00:42

don't print out true then false Now let's look at

00:45

the compared to Yeah all right these two lines of

00:50

code compare the names that we assigned to our two

00:53

objects First it compares george henry We know that g

00:58

comes before age in the alphabet so the total print

01:00

a negative one Next the code comparison henry did george

01:04

while age comes after g and the alphabets of the

01:07

code should print a positive one we know this is

01:09

correct because the only difference between two compared to methods

01:12

is which name comes first so the two calls should

01:16

output opposite values Our output is true False negative one

01:21

one which gives us e as our answer and lawyers 00:01:24.733 --> [endTime] is turning into a real slugger
