vehicle is to be written including the following data members

and method data members representing a vehicle's year manufacturer model

and number of wheels Possessor methods get you factoring in

model All right so which of the following is true

and hear the pencil answer All right well looks like

we're building a super glass called vehicle and creating a

series of variables within it as well as associate id

access or methods to access those variables Right Right Well

the entire point of an accessory method is having it

act as a middleman that retrieves the data held from

a private variable So we can already cross out any

potential answers that suggest we declare any variables Public option

b suggests we declare manufacturer to be a private inner

jer Well the private b**** is right on the money

but an imager isn't gonna work We'll need a string

to store text right there Watching d says model should

be either a private string or public imager to represent

a model number We already know that a public variables

no good But what about private strength Well being that

we're representing a model number and image it would be

preferable here Intend your yeah but wait Couldn't least or

a model number is a string Well it'd just be

a string and numbers instead of an imager But all

in all would it work practically the same right Maybe

Well if we know that our model number variable will

on ly be storing digits it's a little wiser to

use an imager Not only is it impossible to accidentally

insert text into an imager but the imager data type

also used a little bit less memory than a small

strength imager would definitely be the most efficient choice here

So it's a no on the option e says my

years should be a private imager right on the money

and imager would be perfect Thie year will never be

anything other than a whole number and it will always

be a low enough number that we can stick with

the imager data type unless we're still using this program

in the year two billion one hundred forty seven million

four hundred three thousand six hundred forty seven which is

the limit of the energy data type In that case

let's Make a mill note to come back and do

a code on it in about two billion years Deal 00:02:37.613 --> [endTime] or no deal
