Query: Misguided required reading for CS students

Most people who purchase Deitel books do so because it is the required course material for their CS (pick a number) class. Deitel book are needlessly saturated with filler material that do not justify their extremely high cost. You could easily save your money and learn Java by going through the Sun tutorials which are FREE, not to mention the countless online Java tutorials out there (just do a Google search "Java Tutorials"). Stay away from this book! If you have to buy it, then please save some money by purchasing a used book.
