Obtaining Data from an Exception Object
Recall that exceptions derive from class Throwable. Class Throwable offers a printStackTrace method that outputs to the standard error stream the stack trace (discussed in Section H.2). Often, this is helpful in testing and debugging. Class Throwable also provides a getStackTrace method that retrieves the stack-trace information that might be printed by printStackTrace. Class Throwable’s getMessage method returns the descriptive string stored in an exception.
