The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrasing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

The question is why do you catch exceptions at all... Wink | ;)

Most common answer is - to react to specific errors, for example - AccessDenied exception -> show message to user, SQLException - inform about DB problems or retry/abort and clean up..., etc.

In theory if application is properly writen, nothing unexpected should happen. But what if it happens?

You have two options:

1. Allow you OS/Framework show "unhandled exception" message - this annoys end users and makes troubleshooting harder as most users will close the window and will not report the details
2. Catch all otherwise unhandled exceptions and do something with them - log and rethrow or supress with generic error message and app shutdown/restart

Generally in development - this is not very good, unless you have a breakpoint in catch block or rethrow exception in debug config.
In production - I personally think this is good idea. For sure better than "unhandled exception" or empty catch block. Smile | :)
