Working with Java Exceptions ..........................................................................
No matter how skillful a programmer you are, you cannot guarantee that your
program will never encounter an error condition. Various circumstances out of
your control, such as user input, hardware failures, and network outages can
cause errors. A properly written program handles errors gracefully, which
means that it does not crash or cause data loss when an error occurs. Proper
error handling will also prevent an application from bringing the entire system
down when an error occurs.41 448201x-Bonus6 8/13/02 11:23 AM Page 743
