Having had incredible success from The Visual Basic edition of this same title line, I was optimistic about this book. I was quite intimidated by Java but this book has not disappointed me in terms of making me interested and making it easy to learn.
However, I am only now finished with chapter 2 and have found an overwhelming amount of errors in quantity and severity. There are errors in the definitions of primitive types, there is a total mess in one of the code samples… one sample has several lines of code completely reversed, while the comments inserted are the same for one section of code as they are for another section performing the exact inverse calculations! It is an utter mess.
I really hope these errors are cleaned up in the next edition of the book. I’ve already written to the author, and I’ll either want a written guarantee for a free copy of the next edition, or I’m returning the book.
My fear is that as I progress, I will encounter errors that I’m not sharp enough in the language to catch, and will end up with confusion, frustration and time wasted.
So, from what I can tell so far, the book’s technique seems like it will be very successful in teaching me the basics of the language, but if the quantity and severity of errors persist as I’ve seen thus far, I’d have to say that there’s got to be a better alternative.
A person learning something brand new from a book should not have to be the one to discover and correct errors in the book. Who’s teaching who?

First le me say that as a professional developer with 20 years of C++ under my belt I found this book quite useful. It got me up to speed on how building Java applications differs from the same operations in C++. Unfortunately the book appears to be an introduction to java for beginners. I don’t think a real beginner would find it easy to use.
First in most of the book minus signs have been omitted before negative numbers. Thus we are told that a byte has a range of 128 to 127, and a short has a range from 32,768 to 32,767. Anyone who can supply the minus signs doesn’t need the information anyway. I saw some other mistakes I don’t remember, and would probably found more if I hadn’t skimmed many of the early chapters. Maybe the type setting program did this, but why would a company like SAMS let a book with this kind of errors get on the shelves.
If you already know how to program, and just want to transfer your skills to Java you can use this book. Most of the writing is clear, and so far all the code examples I have typed in compile and run. If you are a true beginner don’t waste your money.

I am a certified programmer for java 1.4, and I bought this book on the title alone to get me up to date with the upgrades to version 6. What a disappointment to find that annotations are not covered at all, and generics only partially. Furthermore the collections framework is largely ignored. I looks like a java 1.3 book with some added examples to make it look like a version 6 book, but it is NOT. So if you need a book to study for the certification exam, this book is definitely NOT the one to get.
I found it a complete waste of money.

i just consult the book to clear my doubts.
Thanks.

This is a good book for a beginner who is just approaching Java. They definitely take the “for Dummies” approach here and assume that you have little to no knowledge of programming from the start. The one gripe that I have is that all of the JDK installation and configuration appendices cover Windows only. It would have been nice to see alternate instructions for Linux/UNIX/Mac OS.
