Hi,

I dont know if this answer is "enough".. if not, just reply back

A deamon thread is a service provider for other threads.. [edited away]

JavaWords Introduction to Threads page 3 deals with deamon threads (among other things).

Being a daemon/non-daemon thread, and the thread priority are unrelated concepts. So a daemon can have high or low priority, as can a non-daemon thread.

Of course, often it is true that daemon threads have low priority, because they perform non-critical operations (if they didn't, they should not be daemon threads to begin with).

It is generally recommended that the priority of threads not be changed by the setPriority method (which means it should not be changed at all), and that it should be left to the JVM which thread to schedule.

Hi Ulf, thanks for correcting me. I wasn't aware that deamon threads could have higher priority than non deamon theads.

daemon has relation only to termination VM logic, not priority.
