In our code base, we catch certain kinds of errors - anything that we know could be thrown (for example IOException or NumberFormatException) we will catch.
Most of the time, we don't try to catch exceptions if we don't know they'll be thrown - it's not useful to us to try to catch ArrayIndexOfOfBoundsException or NullPointerException, because generally they imply that there's a bug in our code that should be fixed.
