EDIT: Ok, I've been spending time with the book. I do find numerous confusing points within. Thus, I've found it useful to supplement the book with online tutorials. They are EVERYWHERE! One could probably learn most of what one needs to with those tutorials. But, the book makes a good guide/outline. When I get confused by something, I go look for the same topic in a tutorial. That usually clears things up. If you Google "The Java Tutorials", which are found at an Oracle site, you can find more than you'll ever need to know.
Further, if you search "introcs.cs", look for a Princeton connection. There,I found another very good site that supplements this book well. iTunes university had some java programming video training, as well. As I said, java is everywhere, online.
Mr Cadenhead pretty reliably covers the fundamentals of Java and even gets quite in depth with the language. I think it is safe to say that he goes well beyond what an Intro course would teach for Java. Because of this, if you *really* want to learn Java in 21 days exactly, you can - just be prepared to read, re-read, practice, and practice some more. The pace of this book can be a little overwhelming at times, and I found it useful to hop to the internet for some queries about syntax and definitions that were sort of glossed over (in my opinion). Still, I have learned a lot. It is a great resource and very meaty with information. The exercises are extremely helpful and Mr. Cadenhead provides support on his webpage.
"A variable or method declared without an access control modifier is available to any other class in the same package. The Java Class Library is organized into packages such as javax.swing, which is windowing classes for use primarily in graphical user interface programming, and java.util, a useful group of utility classes.
Any variable declared without a modifier can be read or changed by any other class in the same package. Any method declared the same way can be called by any other class in the same package. No other classes can access these elements in any way."
Perhaps using a Kindle instead of an emulator would solve technical problems then one would only have to deal with the language problems that might be solved with significant editing.
