Question 1: Say that a method catches an IOException in a catch{} block. Is it possible for that block to do some processing and then throw the same exception to the caller?
1. No---when an exception is caught the Exception object is destroyed.
2. No---an exception may be caught only once.
3. Yes---as long as the method also has a throws clause for that exception.
4. Yes---but the catch{} block must construct a new Exception object.
