Thank you We sneak And here's your shmoop du jour
- 00:05
brought to you by forced to fly Certainly not something
- 00:10
you want to hear your pilot complaining about as you
- 00:11
prepare for takeoff All right what are valid reasons for
- 00:15
choosing to create Forced to fly as an interface class

is dead of an abstract flack gnarly near your pencil

answered All right well it's thing option one seems like
- 00:30
a valid choice if objects other than animals were to
- 00:33
fly while the fly method would be different so we
- 00:36
can't implement the method because it would be unique for
- 00:39
different objects Well there's also clears option two If we
- 00:43
declared the method in an abstract class and implemented it
- 00:48
it would be the same across all club crashed up
- 00:51
Option three is also correct because you can't make sub
- 00:53
classes of interfaces but you can with abstract class that
- 00:58
work But if the programmer thought no sub classes would
- 01:01
be necessary an abstract class wouldn't be necessary Yeah well
- 01:06
although you claim that abstract classes aren't necessary jackson pollock 00:01:10.278 --> [endTime] uh might argue with you
