Thank you We sneak and here's your shmoop du jour

00:05

brought to you by module o the supervillain who's so

00:08

evil he eats pie and on lee leaves the remainder

00:11

I consider the following code segment Will an exception be

00:17

thrown If so for what value of i i Well

00:23

the only place where an exception will possibly be thrown

00:26

is when all the operations are being executed on the

00:29

second line of the wild All right if i starts

00:32

at one the expression will evaluate to one over three

00:36

which equals zero You have no exception there i will

00:39

be equal to two Next makes the expression evaluate to

00:43

one over six get no exception Eyes equal The three

00:47

next of the modular expression will evaluate to zero Then

00:50

we have a new one over zero which wait a

00:53

sec can't divide by zero it's a rule that's been

00:56

hard coded into math and therefore the rules of java

00:59

this lionel throw in arithmetic Exception It occurred when i

01:02

was three so he must be our answer I came 00:01:06.291 --> [endTime] down to that pesky mod operation curfew manjula
