Exceptions and Debugging

• Exceptions allow you to work with problems that arise when your software runs.
• They allow you to save work in progress, notify the user, and perhaps give the user a second chance.
• Not all exceptions are user-generated.
• Some can come from poor programming - let's try to avoid these.
• Others may come from the system.  Network failure or losing an FTP connection, for instance.  In this case, you can sometimes set up a recursive retry algorythm.
• And yes, many do come from the user.
• Java's error trapping system is called exception handling.
