In page 54, third line of the last but one para. It says "Dance method extends Sprint...", shouldnt this be "Dance interface extends Sprint" or just "Dance extends Sprint".
In the 5th line it says "Finally the Crawl method defines 2 abstract methods" . this likewise can be ""Finally the Crawl interface..."

Agreed and logged both. I also edited the subject line of your post to reference which book you are referring to. We aren't the only book on the market .
