I have built an application which creates several threads, each of

with a progress bar which will indicate the progress of execution of
these threads (i.e. number of finished threads / all threads in %).
Could you help me with an idea of how to do this?

JProgressBar updated from CountDownLatch.getCount ...

There's section in the Java/Swing tutorial on how to use JProgressBar which you
would probably benefit from reading:
http://java.sun.com/docs/books/tutorial/uiswing/components/progress.html

Also, if you are not familiar with using threads in Java GUI apps. then this
section might help you avoid some of the common pitfalls:
