at java.lang.Thread.run(Thread.java:745) 示例:interrupt()不能中断在运行中的线程,它只能改变中断状态而已。 packagecom.dxz;publicclassInterruptionInJavaimplementsRunnable {publicstaticvoidmain(String[] args)throwsInterruptedException { Thread testThread=newThread(newInterruptionInJava(), "InterruptionInJava"...
java中没有提供任何机制,来安全是强迫线程停止手头的工作,Thread.stop和Thread.suspend方法存在严重的缺陷,不能使用。但每个Thread提供了Interruption中断,一种协作机制来协调线程间的操作和控制。这是JAVA中推荐的方式。程序不应该立即停止,应该采用中断这种协作机制来处理,正确的做法是:先清除当前进程中的工作,再终止。...
Java 中 Thread类 的具体操作与线程的生命周期密不可分,了解线程的生命周期有助于对Thread类中的各方法的理解。 在Java虚拟机 中,线程从最初的创建到最终的消亡,要经历若干个状态:创建(new)、就绪(runnable/start)、运行(running)、阻塞(blocked)、等待(waiting)、时间等待(time waiting) 和 消亡(dead/terminated...
Exception in thread "main" java.lang.Error: Unresolved compilation problem: Unhandled exception type InterruptedException 但是当使用 try/catch 运行时,catch 块中的 sysout 永远不会显示 - 这意味着无论如何都没有捕获到这样的异常! public class SecondThread implements Runnable { ...
// On interruption, re-check runState } } }getTask就是通过WorkQueue的poll或task方法来获取下一个要执行的任务。 回到execute方法 ,execute 方法部分实现: if (runState == RUNNING && workQueue.offer(command)) { if (runState != RUNNING || poolSize == 0) ...
守护线程是低优先级的线程,专门为其他线程服务的,其他线程执行完了,它也就挂了。在 java 中,我们的垃圾回收线程就是典型的守护线程。 它有两个特点: 当别的非守护线程执行完了,虚拟机就会退出,守护线程也就会被停止掉。 守护线程作为一个服务线程,没有服务对象就没有必要继续运行了。
A thread interruption ignored because a thread was not alive at the time of the interrupt will be reflected by this method returning false. Returns: trueif the current thread has been interrupted;falseotherwise. See Also: isInterrupted()
