虚假唤醒会影响Thread.sleep吗?
问题描述：
虚假唤醒会影响对Thread.sleep(x)的调用吗?显然，计时器不是100％精确的(导致唤醒时间略有不正确)，但是它会受到虚假唤醒问题的影响吗?
Do spurious wakeups affect calls to Thread.sleep(x)? Obviously, the timer is not 100% precise (leading to minor inaccuracies in wakeup times), but is it affected by the spurious wakeup problem?
答
You're asking whether Thread.sleep() is affected by the same spurious wakeup issue that is documented to affect Object.wait(long), right? The answer is that there is no documented spurious wakeup associated with Thread.sleep(). You're right that no hard guarantees are made about exactly how long you'll sleep when you request N milliseconds. Also, of course, Thread.sleep() terminates on thread interrupt.
