This week's book giveaway is in the Other Languages forum. We're giving away four copies of Functional Reactive Programming and have Stephen Blackheath and Anthony Jones on-line! See this thread for details.
Very good chapter indeed. Excellent coverage and style. I found one aspect of arrays that is not covered and that is reification. Although is not exactly required for OCAJP, it is an important concept that can set up the ground work for generics later.
I have a feeling this book will give tough competition to all other books, specially k&B
