public static void main(String[] args){
new Timer().schdule(new MyTimerTask(), new Date());
}
为什么程序不能正常推出呢？
new Timer().schdule(new MyTimerTask(), new Date());
}

如果
public static void main(String[] args){
new Timer(true).schdule(new MyTimerTask(), new Date());
Thread.sleep(2000);
}
就可以了。
public static void main(String[] args){
new Timer(true).schdule(new MyTimerTask(), new Date());
Thread.sleep(2000);

i guess if it's a non-daemon thread, it does not need to stop right away.

Once a thread is done, u can not call the start method of the thread object
to rerun it.
Timer is usually used to run the task over and over again during some time
intervals, and it can be shared by multiple threads. finishing task with one
thread doesn't mean the timer thread won't be used by other thread. there
is no good way to tell that if there is a live thread will use it in the
future.
The design can help you save the cost and overhead to terminate and restart
a new timer thread if ever u
to rerun it.

Did you try:
new Timer(true).schdule(new MyTimerTask(), new Date());
【在 A**o 的大作中提到】

yes, then the timer dies as the main thread dies, instantly.
i'd expect timer dies after its completion.
and so did the whole applicaiton shuts down as no timer is pending.
well, anyway, it was a special requirement.

I would still try making the timer itself a daemon, and spawn a non-daemon
thread in the timer task to do the actual work.
