Summary: Good book for C++ programmers, but not for beginners
Comment: If you already have experience in programming with C++, this book is good to learn J++ in relatively short period of time, but if you don't, avoid this book. In my opinion, it's nearly impossible to understand without some knowledge on C++ or J++.

Summary: Not about J++ but Java
Comment: The title of this book is totally misleading. It should have been named "Teach Yourself Kindergarden Java with Visual J++ 6 in 21 Days". As a book for a beginner with no programming experience it would have served its purpose, but it definitely doesn't teach J++ in the way you would expect. Look at the headings.About Java
Day 2. Java Language Fundamentals.
Day 3. Making Applets Live on the Web.
Day 5. Windows.
Day 6. Menus.
Day 7. Applet User Interface Controls.
Day 9. Dialogs.
Day 10. Fonts and Text.
Day 11. Drawing.
Day 12. Images.
Day 13. Image Processing.
Day 14. Animation.
Day 15. Exceptions.
Day 16. Mouse Input.

About J++
Day 1. Getting Started: The Visual J++ Environment.
Day 4. Debugging Java Applets and Applications.
Day 8. Application Controls.
Day 20. ActiveX.
Day 21. J/Direct.
Five chapters specifically about J++ and 16 about Kindergarden Java. Look at the dead air in this book Day 6. Menus, Day 7. Applet User Interface Controls, Day 9. Dialogs, Day 10. Fonts and Text, Day 11. Drawing, Day 12. Images, Day 16. Mouse Input.
Day, Day 18. Strings. I want to learn J++ not Java. I would rather recommend Programming Microsoft Visual J++ 6.0 by Stephen Randy Davis, which is the best book I know about J++ or if you are a beginner, Using Visual J++ 6.0 by Scott Mulloy .

Summary: Good Book for Visual Basic/C++ Programmers
Comment: As a C++/Visual Basic Programmer, I found this book very handy.If you do not already understand the fundamentals of OOP (Object Oriented Programming) then you will struggle a little as it does not thoroughly cover:
- Concept of Classes/Objects.
- Constructors.
- Members.
However, if you already understand these concepts (such as I did), then you will fly through this book with little or no trouble.
This book takes you from beginner to an intermediate level whilst covering the following topics:
- Applet & Application development.
- Use of Dialogs & Standard Controls.
- Graphics & Image Processing.
- Multi-threading & Animation.
- Exception handling.
- I/O Streams.
All examples are easily understood and fairly well explained.
Just don't expect to become a professional programmer from reading this book.
You will however be able to move onto a more advance book.

Summary: I'd give this book 0 stars, but the form won't let me!
Comment: There is little I can say that is positive about this book; I learned one thing about creating a Windows application from it, but otherwise it was wretched. I'll never buy another 21 days book; I didn't have to pay for this one, thank goodness, because it was provided to me as an instructor for a course I was teaching. My students were furious with the quality of the examples, the typos, and the sheer lack of worthwhile content in this book, and it would have been the class from hell if I hadn't found a better text to get examples from. Personally, I would recommend Y. Daniel Liang's book, "Introduction to Java Using Microsoft Visual J++ 6" as a superb text; that is the book my institution is using for next quarter after all the complaints we got on it. If you want to learn any language, here is my advice: Buy a book that teaches the LANGUAGE, not the tool; the tool is largely irrelevant, and with the Visual Studio you will never learn anything if you let the IDE write all your code for you. The tools are nice later on, but get in the way of a beginner.

Summary: Sams Teach Yourself Visual J++ 6 in 21 Days
Comment: I had used other 'Teach yourself' something 'in XX days' before and liked them. I sure got fooled with this one! Avoid this book unless you are already comfortable working with J++. The examples are confusing. It rambles. It presents bits and pieces but never gives you a solid foundation. I really regret buying this book.
