In fact for the vast majority of exceptions it seems to be most common 
to just catch the exception and print it.

Tutorial examples never help, either. They go something like:

try {
   ... stuff ...
} catch (DatabaseException e) {
   print("There was a database exception: ", e);
} catch (NetworkException e) {
   print("There was a network exception: ", e);
}

etc.
