Thank you We sneak And here's her shmoop du jour

00:05

brought to you by abstraction providing away from manic artists

can't implement any and a regular class must implement all

00:37

also today all right choice b seems like it might

00:39

be Our answer statement is actually office and the rules

00:42

of abstract and interfaces abstract classes can contain instance variables

00:47

while interfaces can't let's check the other choices though to

00:50

make sure we've got the right one here All right

00:53

choice sees true both abstract classes and interfaces can have
