People either love the book or hate it. For myself, I think waiting 6 chapters to cover object oriented issues, like how to write a class, is a serious error. Students tend to get "Procedural Brain damage" when object oriented programming is not introduced ealier.The book is not a good reference and becomes shelf-ware after a first read. CS1 topic coverageis OK, but not great. Too much AWT and not enough data structures.If you are looking for a good CS1 book, look elsewhere. Is this product review negative?

input:  Now, answer this question: Title: The Best Sound, however they always break Review: I've never had better headphones than these, once they're in the vaccum of your ear all noise will be blocked out and you'll have the best music experience ever.However they're very delicate. My first pair broke in about a year of usage. Basically I could hear only one side, I suppose the cable broke or disconnected either on the plug or on the speaker.After that I bought a second pair, and I was extremely careful with it, I never put my ipod in my pocket with the headset plugged in to it, I'd always fold it the correct way and keep it in its separate bag.I did this religiously for two years, and about a month ago I was running with the headsets on, and the right speaker stopped working.I wish they'd make them a little more resistant, after using them I've tried to buy other headsets but the sound is crap compared to Etymotic and I guess I'll have to spend another $[...] since without music I'm just not productive at all.
