Is it OK to try/catch something just to check if an exception was thrown or not?

Question

Is it a good way to try something useless just to see if a particular exception is thrown by this code ?
I want to do something when the exception is thrown, and nothing

Answer 1

There's nothing wrong with doing this; after all, proponents of a certain other language are fond of saying "it's easier to apologise than to ask permission", that is, it's easier to wait for something to fail and deal with it than it is to avoid failure altogether. In this case, since there is no alternative, absolutely go for it.
