It's a little hard to tell, but it sounds like you have
some significant misapprehensions about what "static" and
"static synchronized" mean.
I urge you to either get a book on programming with threads
in java[1] or check out one of the tutorials at:
<URL:http://www.apl.jhu.edu/~hall/java/FAQs-and-Tutorials.html>
or preferrably both.
Writing multithreaded programs in Java is easier than in
some languages, but it's still quite hard, and the more
you know about the low level details of the language,
the better.
If I'm misunderstanding what you're saying, and you have
a firm grounding in the details, then ignore the above :-)

Programming in Java"
