Thank you We sneak And here's your shmoop douceur all

00:06

about super classes Did you know that batman graduated at

00:10

the top of his super class It gotham a really

00:13

good job Which of the following method declarations is correct

00:19

Super planets in that access Okay And here your potential

00:25

answers Public private Okay here we go The scenario for

00:31

this question is that we've got a vehicle super class

00:34

with that a member's access or methods for those data

00:37

members and a print method when it comes to actually

00:40

declaring methods we've gotta figure out which of the potential

00:43

answers is correct Access for methods aren't a must have

00:47

your program would technically run using public variables and accessing

00:51

them directly from wherever you like But it's messy excesses

00:54

add another layer where you can insert extra code to

00:57

insure data is accurate formatted correctly or being protected in

01:01

some other way Let's get rid of the private options

01:03

b and e right off the bat The entire point

01:06

of an accessory method is to be public in access

01:09

privately held data for us So as for option a

01:12

part of declaring a method is specifying what data type

01:15

is returned if any just saying public print is no

01:19

good option c declares get manufacturer as a public method

01:23

a good start but it says the method will return

01:26

an integer imagers is we know we're just numbers that's

01:30

not going to do us a lot of good when

01:31

we try to return the name of ah manufacturers are

01:34

option d says avoid meaning It won't return anything at

01:38

all That's Perfectly fine The print function will be printing

01:42

data to the consul and we won't need to return

01:44

any values after calling the method So uh option d 00:01:48.858 --> [endTime] is the hero we deserved Oh
