Invoking JDialog on every exception

Question

Hello,
In my application I want to a feature that would show up a dialog when an exception (checked or unchecked) is thrown.
The simpliest solution - putting all of main() in try/catch block, and adding dialog code in every catch, is not very good I guess - code inside try/catch executes considerably slower (I read it in Effective Java by Joshua Bloch), so what is the right way to invoke dialogs on exeptions??

Answer 1

That's true. The performance overhead is non-existant. I remember reading somewhere that in the case that no exception is thrown it is indeed zero (null, nada, zip, ...) but I can't be bothered to find that place right now. And even if it isn't really zero it's near enough to be seen like that for every practical purpose.
