Query: Discourages more aspiring Java Programmers than Bill Gates

This book is full of typos, ambigous statements, faulty example code and leaves the reader wishing they had bought a different book. My biggest complaint is the lousy examples in the later chapters: apparently, the Deitels decided to gloss over some important topics, like file streams, giving you a 400 line "Example" program, with sparse explanation. Deitel and Deitel decided to slack off near the end of the book, for who knows what reason. If you can't program in a language you shouldn't be writing a book about it.
