I have a process p = Runtime.getRuntime().exec("some programe). After a
timeout(say t), I need to stop this process if it haven't finish running.
What's the nice way to do that?
Thanks!

check javadoc. I believe it must be there.

No way from Java. But you can call native function/command to halt
your process.

Thanks!
Now I found out I can't tell if the process's status after t. If I do
p.exitValue(), it throws IllegalThreadException. If I do p.waitFor(), it
ignores my timing while loop. What I did in my code is:
while (System.currentTimeMillis() - startTime < t)
{
if (p.waitFor() == 0)
break;
}
Could you advise?
Thanks!
