only by catching or by using a querying method of some kind to determine if an exception is likely to be thrown.Hi,
I want to check if a statement throws an exception. If it does, I want to deal with it then and there, and not at the catch claus. See code below:
.... String[] str = {"dinner"}; if (str[1].charAt(0) throws ArrayIndexOutOfBoundsException) // compile error { //do something 1 } else //do something 2
Is this possible?
Sharp Tool
e.g
instead of ...
if (str[1].charAt(0) throws ArrayIndexOutOfBoundsException) // compile error
do...
if (str.length > 0) str[1].charAt(0)
This way - no ArrayIndexOutOfBoundsException will be thrown because of the length is too small we don't try and get the first element.
