Hiya, I'm having some problems with threads. I'm using the JDK to develop
some sorting demos (bigger and better than the existing demos). I run the
sorting algorithm in a thread, when the thread goes to sleep, I update
the display. Anyhow, If I make the sorting thread a daemon thread it
doesn't work! Thus my first question:
Q) What is the difference between daemon and non daemon threads other than
that execution of a program will stop when all non daemon threads are
finished?
I would also like to be able to kill the sorting thread. This happens if the
user wants to restart the demo, I want to kill the current version of the
sort thread, and then make a new one. I'm doing this in the handleEvent
method currently.. (that is I am trying to do it there, but its not working).
This leads to my second question:
Q) What is the recommended way to kill a thread that is executing? My thread
makes calles to other threads. I would like to be able to kill the thread
without waiting for the function call to return (if this is possible) and
in another case I would like to wait for function calls to complete before
the thread dies.
TIA, Bindu
