I've caught an exception!! Now what?

Question

I\'ve started using try-catch blocks (a bit late, I know!), but now I\'m not sure what to do with the exception once I\'ve caught it. What should I do?

Answer 1

Well, That depends primarily if you are making money from your application or not. By my experience, nobody (who paid for an application) likes to see it crashing and closing, instead they prefer a short and explanatory message about the error and a second chance to continue whatever they were doing plus a chance to save/export their modified data. IMO a best practice is to catch everything that can cause something wrong out of your control, like I/O operations, networking related tasks, e.t.c. and display a relevant message to the user. In case that an exception is thrown due to a logic related error is better not to catch it since this will help you to find and correct the actual error.

Hope this helps.
