## Request for Comments

We invite you to help us improve our books. If you have an idea that could make this a more useful language reference, or if you find a bug in an example or an error in the text, let us know by sending mail to bookquestions@ora.com.

As Java continues to evolve, we may find it necessary to issue errata for this book or to release updated examples or reference information. This information will be found on the book's web site, http://www.ora.com/catalog/javafund/.
