Call the interrupt() method on your thread. This will cause the sleep to be cancelled and an InterruptedException will be thrown.

You can interrupt a sleeping thread with <code>Thread.interrupt()</code>. Now stopping a thread is deprecated - what if the thread is holding a lock to something? (There was a <code>Thread.stop()</code>, but it is HIGHLY discouraged).

Alternatively, instead of sleeping, you can have your thread wait for an object to be notified with a timeout, and simplify notify the object if you want the thread to wake up.

blocks|key|1082469|text|Suresh，我想关注一个问题。interrupt()方法本身不会中断线程。它只是通过将标志设置为true来向线程发送中断请求。通常你的线程应该处理取消/中断策略。它在Java+Concurrecy+in+Practice的第7.1节任务取消中有很大的描述。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1082470|像Thread.sleep和Object.wait这样的阻塞库方法会尝试检测线程何时被中断并提早返回。它们通过清除中断状态并抛出InterruptedException来响应中断。|1082471|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Suresh, I wish to pay attention to one issue. interrupt() methods itself does not interrupt thread. It just sends a request to a thread for interruption, by setting the flag to true. Usually your thread should process cancellation/interruption policy. It is greatly described in Java Concurrecy in Practice, section 7.1 Task Cancellation. 

Blocking library methods such Thread.sleep and Object.wait try to detect when a thread has been interrupted and return early. They respond to interruption by clearing the interrupted status and throwing InterruptedException.

blocks|key|867793|text|因为我不能评论，所以我会发布另一个答案。我只想强调和澄清Alexandr说过的话。interrupt()只在Thread中设置一个标志，扩展的Thread或Runnable对象必须检查它是否被Thread.interrupted()中断，以便在中断时做它应该做的事情。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|867794|interrupt()还会停止wait()或sleep()，但请注意，这些方法不会设置中断标志。因此，如果你在睡眠/等待线程上调用interrupt()，它将停止睡眠/等待，但不会知道它被中断了，除非你捕捉到了异常，并且不会继续被中断。|867795|我能够通过实现我自己的中断标志来修复我的程序，它不能被sleep()和wait()方法覆盖。此外，要知道您可以使用Thread.currentThread().interrupt()从内部中断线程。|867796|entityMap^0|15|B|1I|6|1Z|6|26|8|2O|K|0|0|B|F|6|M|7|1T|B|0|R|7|Z|6|1L|Y|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@$9|X|A|Y|B|C]|$9|Z|A|10|B|C]|$9|11|A|12|B|C]|$9|13|A|14|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|15|8|@$9|16|A|17|B|C]|$9|18|A|19|B|C]|$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|1C|8|@]|D|@]|E|$]]]|K|$]]

Since I can't comment, I'll post another answer. I just want to reinforce and clarify what Alexandr said. <code>interrupt()</code> only sets a flag in the <code>Thread</code>, and the extended <code>Thread</code> or <code>Runnable</code> object have to check if it have been interrupted with <code>Thread.interrupted()</code> to do what it's supposed to do when interrupted.

<code>interrupt()</code> also stops a <code>wait()</code> or <code>sleep()</code>, but pay attention that those methods UNSET the interrupt flag. So, if you call <code>interrupt()</code> on a sleeping/waiting thread, it will stop sleeping/waiting but will not know that it was interrupted, except if you catch the exception, and will not continue to be interrupted.

I was able to fix a program of mine by implementing my own interrupt flag, which couldn't be overridden by the <code>sleep()</code> and <code>wait()</code> methods. Also, know that you can interrupt a thread from within with <code>Thread.currentThread().interrupt()</code>.

How to stop or interrupt a sleeping thread in java.? I have a thread that syncs data and sleeps for 10 minutes in run() method, if i want to stop the sync by stopping the thread when it is sleeping.? How can this be achieved?

Interrupting or stopping a sleeping thread

如何在java中停止或中断休眠线程？如果我想通过在线程休眠时停止该线程来停止同步，我在run()方法中有一个线程可以同步数据并休眠10分钟。如何才能做到这一点？
