You can't restart a thread. From the javadoc:
"It is never legal to start a thread more than once. In particular, a
thread may not be restarted once it has completed execution."
Does legal mean the code won't compile or that it just isn't good
practice? I ask because I have a class that contains a run() for a
thread and I call it everytime I need to do the operation that the run()
performs and I do so w/o creating a new instant of the class that the
run() is a part of. So far I haven't seen any problems with that
approach. Is that not the same thing as what the original poster was
trying to do?
You have lots of choices to get the effect you want. You can
create new threads to pick up where the dead threads leave off; better
would be to use one of the java.util.concurrent.* classes from 1.5 if
possible to provide a thread pool. There are other goodies in
java.util.concurrent that you may find helpful as well. If 1.5 isn't
an option for you, you still have a lot of flexibility, it just won't
come nicely wrapped with love from Sun - you'll have to write
something to suit your needs yourself.
