虚假的唤醒会影响Thread.sleep吗？

Question

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?

Answer 1

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.

Answer 2

real interval of sleep is always >= required interval. it is especially sensitive on small intervals.

now about "spurious wakeups". it was not mentioned about Thread.sleep
