Question

I have third party libraries being used in my application and I don’t know what exceptions they can throw, obviously from debugging and use I can work out some of them but not all.

So, is there a way to know what Exceptions could be thrown without documentation?

Failing that, I know I can catch (Exception) even though most guidelines recommend against that but if I don’t catch them will they just bubble up through to the top exception handler? Is there any reason why they wouldn’t be able to be handled in this way?

Answer 1

Without documentation from the third-party library, there’s no way of knowing exactly what Exceptions will be thrown.

Any un-caught Exceptions in your code (like you mention) will bubble up to the top handler. I wouldn’t suggest blanket catching all Exceptions though (unless it is a top level logger or something similar). You should really only be handling Exceptions that you can recover from.
