Is there sample code or a tutorial on how to use
java.util.concurrency?

I would like to figure out how to schedule short work packets to be
executed by perhaps 30 different threads, with some sort of mechanism
to dynamically increase or decrease the number of threads to improve
performance on that particular machine. This is for linkvalidator
spidering program similar to Xenu.

to use it.

It is called java.util.concurrent.Executors.newCachedThreadPool

You should be able to find plenty on that. Sounds like fun. Good luck!
