Exceptions were designed for ? • Program has encountered a serious error, and getting out of this control flow to prevent data corruption or other damage is more important than trying to continue onward handling if the event doesn't occur often, that is, if the event is truly exceptional How much of your flow (upper-bound) should be taking exception paths ? • Does anyone measure this ? How do I handle “frequent” Exception is in a loop and has a conditional rethrow; Conclusion : Use a return status for loop control 37 Bloomberg Exceptional TrierSituation : Any problem whatsoever, throw an exception.
