Looking for tutorial material on 'static', 'final' et al.

[Ramon F Herrera]

My background is in Unix C programming, so bear with me...

When I get error messages such as:

"Cannot make a static reference to the non-static field <xyz>"

I am able to move things around and make the program work. I do have a
rough idea about the issues involved, but I would like to take a
deeper dive into it, and reach a level at which I can predict the
above class of compilation problems before they I introduce them in my
code. Is there any concise, specific explanation around?

"Cannot make a static reference to the non-static field <xyz>"

see

http://mindprod.com/jgloss/static.html
http://mindprod.com/jgloss/instance.html
http://mindprod.com/jgloss/final.html

etc. Just look up the word of interest in the Java glossary and
follow the links.
