Sorry On here's your shmoop du jour about to convey

00:06

some knowledge and maybe erection Hear that All right this

00:11

code is a method for a sequential search through an

00:14

array list called ah list Clever title Well what should

00:19

go in expression to to complete the method this expression

00:24

here time and here your potential answers What do you

00:28

think Value value All right here we go Okay well

00:33

this code is pretty simple Sequential search the four loop

00:36

the finer points of which we've covered in the previous

00:39

question iterated through an array list and the if statement

00:43

will check each element to see if it's equal to

00:46

the imager called number that we were looking for donald

00:49

that alright well having covered expression one in a previous

00:52

question looks like this by the way were now being

00:55

asked for expression too or do if you're in paris

00:59

and really clever All right if the four loop is

01:03

the conveyor belt that brings us the next item down

01:06

the line the if statement will be the bit that

01:09

looks for a match You know like jd we're being

01:13

asked what the structure of the if statement should be

01:16

options And beer both out They use standard array style

01:19

brackets to refer to elements a rainless require using the

01:23

get method to retrieve stuff As for picking apart option

01:26

c and d well the objective here is to return

01:28

a true or false for the if statement toe work

01:31

with with option d there's a conditional operator present within

01:35

those parentheses a double equal sign which will check if

01:38

the two items are equal and return a true or

01:42

false Got it well then it attempts to shove that

01:45

whore false into our values variable which is an imager

01:48

It's where bag meat round hole not good option c

01:52

copies the current element in a list to the variable

01:56

value here then checks If it's equal to the imager

01:59

number which is the number we're looking for The result

02:03

of this statement would be a true or false that

02:05

would enable the if statement then either execute the code

02:09

inside it's blocked or not All right there is the 00:02:12.91 --> [endTime] answer I don't know
