If the file cannot be found, the exception is caught in the catch-block. In this example, the error handler simply prints the stack trace, which provides useful information for debugging. In some situations, you may need to perform some clean-up operations, or open another file instead.

For example, a floating point divide by zero exception will typically, by default, allow the program to be resumed, while an out of memory condition might not be resolvable transparently.
