I would like to meet Laura Lemay (the main author) to ask her three questions:1) Why are there so MANY typos and errors?2) Why did you name the book 'Learn Java 1.1 in 21 Days' when much of the book covers Java 1.02?3) Why are there so MANY typos and errors? (or did I already say that? hint hint)The reality is, the book is not bad, but it really suffers from bad editing, a preoccupation with Applets over Applications, and wastes FAR too much time covering the JDK 1.02 (considering the title says it is covering JDK 1.1). The first week or so was well written (again, not counting the typos and sloppy editing), but some chapters were far too long to reasonably cover in one day.My recommendation is that you look at the Core Java Series books (vols I & II) and at Just Java and Beyond (all three are VERY well written and are much more robust than 'Learn Java 1.1 in 21 Days').
