Re: Join thread with SwingWorker objects

You might look at the examples in the SwingWorker API [1] and this
similar database example [2]. In the latter, the generic type V is
Double, and individual instances are published from the background
thread. Note that the List<Double> received by process() is _not_ the
same List<Double> returned by doInBackground(). The former contains
intermediate results; the latter is the background thread's working
result set.
The method doInBackground() can create other threads, but you still have
to synchronize their processing, as others have suggested.
