Sorry And here's your smug too Sure Brought to you

00:05

by parentheses there like little hugs You give your computer

00:09

Oh what's The computers sometimes rejects you know like children

00:14

Alright this code is an implementation of a sequential search

00:18

What should go in expression One to satisfy the conditional

00:21

statement That's history Got it right here Potential answers equals

00:28

and yeah that's gotta be it Okay All right Well

00:31

remember those math word problems where the buildup would get

00:34

really convoluted and try to overwhelm you with information Just

00:38

a cloud A simple question like jenny and tony started

00:42

a fruit stand gather jenny is selling the oranges she

00:44

grew which cost ten cents apiece to grow over four

00:47

months She's now selling them for twenty five cents apiece

00:49

that the average rate of twenty per hour Meanwhile tony's

00:52

juggling three apples and dropped one How many apples is

00:55

tony holding Yeah same sort of thing Here we're being

00:58

given a big rambling thing about a search method and

01:01

expressions and conditional statements But looking at the possible answers

01:05

it's pretty obvious We're on lee really being asked how

01:08

to get the number of elements in an array list

01:12

got it all right Well this is one of the

01:14

ways in which standard arrays differ from array list Object

01:18

arrays have a very simple very useful attribute called length

01:21

No joke there that you can look at which will

01:24

return The number of elements in the array goes a

01:26

little like this Yeah but a raylan aren't your usual

01:31

arrays and don't have that exact attributes Instead there's a

01:34

method called size Yeah that's The call with empty parentheses

01:39

Not very different but it goes a little like this

01:43

Which brings us back to our potential answers The way

01:46

to get the array list size is only properly done

01:49

in si size with the empty parentheses or you know 00:01:53.508 --> [endTime] hugs Oh
