In the discussion of GetHashCode on pp. 80-81, the authors state that the "hash code should be based on immutable members". Yet, in the example, it is partially based on the "balance" member, which doesn't seem immutable to me. Am I missing something here, or is there an inconsistency between the rules and the example?

Thanks...

P.S. BTW, I'm finding this book well-written, concise and informative in a detailed way.

I don't understand. This a Wrox book which clearly states on the front of it: "Peer discusion at: p2p.wrox.com". What does Wiley have to do with it.

You do indeed have a Wrox Press book in your hand, but you must be unaware of the recent turmoil having to do with Wrox. Wrox went bankrupt in March 2003 and its remaining assets were put up for sale with a liquidator. Wiley Publishing (who now maintains the P2P site and Wrox.com) purchased a selection of books, the right to use the Wrox name and brand, and some of the website capabilities. The book that you have was not one of the books purchased by Wiley. The remaining books not selected by Wiley were purchased by Apress publishing.

Wiley maintains the P2P discussion site, but you will only find book discussion groups for those we purchased. We do have the "Other Wrox book" group for the other books, but we do not guarantee author feedback or tech support. But, in all likelihood, a member of the list will be able to help you.

Thanks Jennifer. Does Wiley plan to continue publishing future books along the lines which Wrox did?

Yes, we are currently working on revising the books that we acquired as well as signing unique works that fit. If you wish to learn about upcoming books and promotions, please feel free to subscribe to our monthly Wrox Press Newsletter (see link at top nav bar).
Thanks so much for your understanding!

Does wiley plan to offer promotions that Apress does, for example like if you get 5 Apress books you get 1 book free. Not quite sure how many books it was, but something to that effect. And would the quality of Wiley be the same of previous wrox books or maybe with less errors and typos.

Program or Be Programmed!!!

Wiley and Apress are two separate publishing companies, so our promotions are different. Wiley does spend an enormous amount of money for cooperative advertising with our bookstore accounts, and will continue to do so. In fact, Wiley just completed a Wrox promotion with Amazon.com where all of our Wrox books were 35% off from 7/16-7/22 (if you receive the Wrox Press Newsletter, you were notified of this). Wiley has also arranged for many promotions for the Wrox books with our national accounts over the next few months - one of which will be posted to P2P's announcement section this Friday.

As for the continued quality of the books, Wiley is committed to upholding this standard of quality.

Thanks for your interest.
