Simple logic, really.

Exactly! No exceptions thrown.

Brice 1 month ago

So, option D is correct then?

Willetta 1 month ago

I agree, it's clear in the code.

Nathalie 2 months ago

But it won't, default case handles it.

Maia 2 months ago

I feel like it should throw something.

Javier 2 months ago

Yeah, because 4 doesn't match any case.

Chandra 2 months ago

I think it prints: No exception.

Kina 2 months ago

I thought it would throw something for sure!

Yvonne 2 months ago

Yup, that's what I got too!

Alverta 3 months ago

Wait, are you sure? What if there's a hidden exception?

Shawn 3 months ago

Totally agree, default case handles it!

Moon 3 months ago

It prints: No exception

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!

Teresita 3 months ago

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?

Carmela 4 months ago

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