Hurry And here's your shmoop du jour brought to you

00:05

by the boolean doctor When the mother asked if it

00:08

was a boy or a girl he just said yes

00:10

Open which of the following options will satisfy the conditional

00:14

if statements for booster and i respectively and area potential

00:18

answers All right we could eliminate a because incorrectly compares

00:26

strings You can only double equals operator on primitive types

00:30

with strings you must use that compare to method So

00:33

there's also eliminates the e He seems correct using the

00:37

compared to method and then comparing those values Zero Well

00:41

this is the correct way to use the compared to

00:43

method c is correct because it doesn't compare the value

00:47

returned by the compared to method to anything Remember that

00:50

compared to method returns and manager not a boolean It

00:55

looks like he's our answer Next time we're looking at

00:57

ten kinds of people in the world those who understand 00:01:00.31 --> [endTime] binary and those who don't
