Java Book online; Java 5 Extension Summary

I've just found this book online.  As far as I can tell, it seems to be
equivalent to the (paper) book "JavaTech: Introduction to Scientific and
Technical Computing with Java" -
http://www.particle.kth.se/~lindsey/JavaCourse/Book/index.html

All the chapters seem to be available by clicking at the bottom of the page.

One particularly useful chapter/page was the following summary of new
features in Java 5 -

Java Language Spec, Enum Restrictions

From: "andrew cooke" <andrew@...>

Even so, there's insufficient detail on Enums (just got an error saying I
cannot access a static field in the class from within a constructor -
that's Enum specific, right?).

Hmmm.  The JLS is available for download -
http://java.sun.com/docs/books/jls/index.html - and the justification for
this restriction is descibed on page 252.  It's not a very good
justification, as the rule is more general than the problem (avoiding
circular references of Enums), but I get the impression there's a whole
mess of special cases because the language is getting so complex.
