Thank you We sneak and here's your smoke Do george

00:05

brought to you by way give up our we supposed

00:09

to keep thinking of all these puns Wait just All

00:15

right consider the time class public land private our minutes

00:23

For many things alright we would like to write a

00:25

subclass twenty four hour time with added functionality in order

00:30

to meet all of your international travel needs which of

00:33

the following is false true let's go through well choice

00:41

a states that the subclass will inherit the basic functionality

00:46

from its super class This is the basic definition of

00:49

what a subclass does so must be true He is

00:54

also true Because subclass is inherit all of their super

00:57

class methods Those super class methods can be performed on

01:01

subclass objects You can also say that choice see is

01:04

true because some plus objects can always be stored inside

01:07

of their super classes but not the other way around

01:10

Well choice t seems like it might be falls It

01:13

states that twenty four hour time methods can access time

01:17

data members well let's Look at the time data method

01:21

well all three of them are declared as private recalled

01:24

it Outside classes never access private data fields even some

01:28

classes over inherit all the private data They could only

01:31

excess them through getters All right well seems like these

01:37

are answer but let's See why Choice he's True it

01:41

states that the print method in time can be overridden

01:44

by different new print method in twenty four hour time

01:48

Well this is a given property of sub classes if

01:51

they need to change and inherited method to suit their

01:54

needs While the computer allows it no promises will be

01:58

able to avoid using more bad months in the future 00:02:00.84 --> [endTime] So watch out Look
