Laurie and here's your smoke usually brought to you by

00:04

the private declaration of album names because you don't always

00:08

want your friends to know you on them All right

00:10

consider the following declaration album A equals new album Kind

00:14

of blue miles davis nineteen fifty which of the following

00:18

are objects okay And here your potential answers brought to

00:23

you by and let's go alright So java is an

00:28

object oriented language but that doesn't make everything an object

00:32

But some things are somethings are look the objects around

00:35

you right now No seriously like what do you got

00:37

Lamp bicycle autographed photo of the nineteen eighty nine oakland

00:40

athletics where jose conseco misspelled his own name on steroids

00:45

Yeah good us to write Each one of these is

00:48

an object with its own states and behaviors thing about

00:52

the bike it states could conceivably be things such as

00:55

its current speed current gear speed like here and whether

01:02

or not it's currently getting any sick air and it's

01:06

behaviors or functions It could do changing gears turning left

01:10

or right and so on The objects can be pretty

01:13

complex things different from objects though our classes and primitive

01:18

data types are a class isn't an object It's more

01:23

like the instruction manual from which objects are constructed An

01:26

object is an instance of a class all right it's

01:30

A lot like a recipe A cake recipe shows you

01:32

everything you need to make a huge gnarly cake The

01:35

recipe is not a cake object itself Primitive data types

01:38

are also not object Imagers long's floats bites There are

01:43

eight in all and they're just bear data that come

01:46

with none of the interesting stuff that makes objects on

01:49

objects Those faras this question is concerned We have three

01:52

players and were asked which of them are objects album

01:55

album year and uh well starting at the top album

01:59

is the class in question and we know that classes

02:02

are objects so we can cross that baby off strike

02:04

one album you're sure sounds like an object but it's

02:07

not looking back above album here is just an imager

02:11

Well manager is being primitive Data types are just a

02:13

bit of data Strike two a however is an object

02:17

declaration here Album a equals new album creates a new

02:21

object of the album class named eh that means our 00:02:25.045 --> [endTime] answer will be See Three only conform
