This book never comes close to presenting istself as a stand alone subject for learning java. Especially not in 21 days or 100 days, I would challange if it could be done in a year. This book is poorly written with enormous amount of errors , not just in the text but in the program listing themselves. I doubt if this book was proof read or even if any of the programs where written and carried out to the extreme to see if they really worked. While this book covers a lot of topics there are poor to no examples on any of the material that is covered.

This book alone with the second edition is being used for a subject class for a college level course. The second edition is not as bad as the first , tho , what are the odds of the same program appearing in both books and in different formats and yet neither one will run when you get done. Well you just have to present them to the instructor and ask him to give it a go . oh! it wont run . maybe we ought to throw out the books. Heres an idea lets get hold of the auther , you mean they wont answer there email. WOW , and to think we buy this junk and nobody ever sits down and looks it over. Simply amazing. so if you are interested in java , i know two books at least to stay away from.

i have a library of several books that i use for reference, and i could not at this time recommend one. If there is someone out there who has some great degree of results let me know . It could also help others.

If i had to choose one it would be the " complete reference of java by Naughton / Schildt ". while not the best it does answer a lot of questions.

learing java you need to really be exposed to layouts ,events networking and windows. this book falls short on all accounts.

yes i am still working on java , i like the langauge and will learn it one way or another .

so happy programming to one and all.

do drop me a line

I tried learning Java from this book and failed. Perhaps I shouldn't blame the book but rather my lack of previous experience with object-oriented programming. In any case, this book did not cover object-oriented design sufficiently or clearly enough for it to click. If you already have this background, perhaps this book would be of more use, but if you are trying to learn Java and have never taken C++, Pascal, or any other object-oriented language, I would look for another book.

This book is indeed a little difficult to understand. Unless you know C and or C++, it is hard to understand. There are indeed errors in the book. Is this some sort of trickery in order to be able to continue to come out with a 2nd, a 3rd, a 4th, etc. editions?

Wow this book sucks... unorganized and incomplete. The most common line was "you will learn more about that later on day xxxx"

STAY AWAY FROM THIS BOOK

The title is misleading: I was looking for a quick way to learn Java and was very disappointed. The book is filled with irrelevancies. Stay away from it if you're in a hurry. Hint: look at the number of pages...

I found the book was good for me as I have experience with C++ programming. It may be hard for a beginner as it seems to be really geared for someone with C or C++ experience. I found the book still relevant, although the UI programming uses AWT examples. I was able to compile and use Java programs using the Java SDK in no time and even got applets running in a browser.

For someone that has no programming experience in an object oriented language, I can see how this book would be difficult. It does indicate on the back cover that it isn't for new programmers. Topics about inheritance and the pointer-like variables in Java would drive you nuts. The author tries, like everybody else to explain classes in pretty much the same way as everybody else (motorcycle, car, etc.). I wish there were more programming projects or hold-your-hand creating programs content.

I bought the book because it was cheap and I am really happy with it. I found it much better than the "Teach Yourself C++ in 21 days" book I bought a while ago (I had to use a different book because of the namespace weirdness in that one).

I am a beginner,I want to learn java quickly.but this book cann't
help me to do this.

I have two beginning Java books, Joyce Farrel's "Java Programming: 2nd Edition" and "Teach Yourself Java in 21 Days" of the two, this book is the easier to understand. However, it doesn't push the reader to experiment with code and push themselves like the first title I mentioned does.

I have experience in other OOP languages and that may be what made this book easy for me to understand. If I try to look at this book as a beginner that has never had any programming experience I think this book would be tricky to understand. I would suggest that anybody that wants to learn any kind of programming get a good book on programming logic and learn how to write pseudo-code and flowchart before they totally imerse themselves in OOP (or procedural programming).

This book does cover almost every aspect of Java. The one that I found it lacking in, and the one I need for work, are JDBC basics. Still, I think that before tackling JDBC a person should understand the basics and this book would do a good job of that.

I have had two people recommend "Thinking in Java" by Bruce Eckel as the best book for learning Java. I have not read it but it is free for download in PDF format. I think a book like that combined with this one would be the best for anyone that wants to be a Java programmer.

This book is a fairly good book if you have experience in C++. If you don't know object-oriented programming, my advice is to start from the beginning. Learn C/C++ first!!!!!

The book serves its cause. The only problem is that the chapters are not evenly distributed.

And when you want to learn it "by the book", you need 28 days, not 21. See page 2.
