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
