Thanks everybody. Just to let you know, the web page for the book is
http://shop.oreilly.com/product/0636920056669.do, but O'Reilly Media recently decided not to sell books directly from their web site. Instead, they would love for you to get a trial subscription to Safari Books Online, which would give you access to all the books, as well as videos and online training courses. I'm a fan of that, having been a Safari subscriber for years.
That said, if you want to purchase the book directly, it's available at Amazon at
https://www.amazon.com/_/dp/149197317X, Barnes and Noble, Books A Million, Google Books (
https://books.google.com/books/about/Modern_Java_Recipes.html?id=z0AsMQAACAAJ), iBooks, and more, all at a discount.
