But it won't, default case handles it.

Yeah, because 4 doesn't match any case.

I’m a bit confused about the catch blocks. If it hits the default, does it really just print "No exception" without throwing anything? That seems too straightforward!

I practiced a similar question where the default case was also involved. I feel like it should just output "No exception" since 4 isn't one of the cases.

I'm not entirely sure, but I remember something about exceptions being thrown for specific cases. I guess 4 doesn't match any case, so maybe it just skips to the default?

I think if character 4 is input, it goes to the default case, right? So it should print "No exception".
