Thank you We sneak and here's your smoke du jour

00:05

brought to you by primitive data types Careful they bite

00:09

Consider the following declaration Doubleday is one point six one

00:14

eight string act is just moving true art which of

00:19

the following is an object and wrong time Your potential

00:23

answers Arthur now just what in the sam hill is

00:30

what you might be saying especially if you're an old

00:32

timey gold prospector Well java is an object oriented language

00:36

Doesn't that mean everything's an object Well not quite There

00:40

are objects that contain data but they're also primitive data

00:44

types in job there a primitive data types to choose

00:47

from so don't worry about memorizing them all But what

00:50

sets them apart from objects is that they're composed of

00:53

no other data types and can't be broken down any

00:56

further their basic unbreakable building blocks like the atoms of

01:00

the programming world you know Well pirate in nineteen forty

01:03

five Come on Okay so double and julian are primitive

01:08

data types And on lee contain data But string is

01:12

an object that contains data as well as some other

01:14

stuff Ride java string apart and you'd find that it's

01:17

actually an array of character primitives wrapped up in a

01:21

single object along with some methods for accessing those characters

01:25

Yeah charge Ok it's Not quite like comparing apples to

01:28

oranges it's More like comparing apples the boxes of apples

01:32

and some other stuff Your answer is b two on

01:35

lee But why Why even have permanent data types at

01:38

all Why didn't jobs creators just make everything an object

01:41

and leave it at that well efficiency reasons with an

01:44

object you could wind up allocating memory in unpredictable ways

01:48

Primitive data types are straight forward Each one has a

01:51

specific size that it'll take up in memory no necessary

01:55

when you're working with lots and lots of individual values

01:58

but use an object with all the methods and baggage 00:02:00.985 --> [endTime] that comes with it And well oh boy who
