AP Computer Science 3.5 Classes and Objects

following is not an object In case we get year

ok and hear your potential answers Okay where we where

we live think right again We go back to the

differences between primitive data type can an object classes and

primitive types are not objects And when we talk about

primitive types don't mean grandpa hunt and peck methods in

java There eight primitive data types Remember imagers which store

the whole Numbers in 32 bits of computer memory In

practical terms that means a number of a positive or

negative value of around two point one Four billion with

a b plenty for most uses but its whole numbers

on leah's faras energies are concerned A long is just

like an imager But using sixty four bits of memory

that amount of space could represent a value of over

nine Quintillion again the whole numbers only and if along

Is a longer imager Well you might guess that a

short would be a shorter in inger lever and you'd

be exactly right there you get just sixteen bits to

do your bidding resulting in numbers up to greater than

about thirty two thousand a bite is even shorter than

that eight bits sign that gives you a maximum value

of one hundred twenty seven These smaller data types can

be used to save space in situations where you need

to start a lot of smaller values William data types

are very simple and store only a true or false

value Char stores a single sixteen unicode character or here

meaning practically any alfa numerical punctuation mark symbol or foreign

language character and floats and doubles are floating point values

Floating point values aren't quite exact representations of real numbers

They're more like an approximation but allow you to get

too deep with decimal places good for some things but

when precision is required such as one working with money

use energy instead So far five given declarations which is

not an object alvin j equals new album yet we're

creating a new object of the album class and it's

Called j well this one's an object so it's not

our answer by the way in sync what about backstreet

her and seeing had a couple hits but justin timberlake

was carrying that whole outfit like paul mccartney All right

well string k equals yada yada Well this too is

an object Drinks aren't a primitive data type Their collection

of char data type in array with a few methods

tagging along totally an object during l equals yeah same

thing here drink in equal j get name l that's

an andre too and that leaves into em and as

we know it are not objects their primitive data type

so it leaves us with just option d that's the

answer and a newfound respect for backstreet fact Three back 00:03:07.53 --> [endTime] all right No
