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

brought to you by an angry snail What the shell

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
