我正在通过kathy sierra SCJP 1.5第9章(线程),它被提到：
Notice that the sleep() method can throw a checked InterruptedException
(you’ll usually kNow if that is a possibility,since another thread has to explicitly do
the interrupting),so you must ackNowledge the exception with a handle or declare
我只需要一个示例程序来了解它何时发生(我可以在我的机器上运行)？
我用Google搜索但找不到任何示例代码来测试此功能..
提前致谢
解决方法
这是一个例子：
public class Test
{
public static void main (String[] args)
{
final Thread mainThread = Thread.currentThread();
Thread interruptingThread = new Thread(new Runnable() {
@Override public void run() {
// Let the main thread start to sleep
try {
Thread.sleep(500);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
mainThread.interrupt();
}
});
interruptingThread.start();
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
System.out.println("I was interrupted!");
}
}
}
要完成它：
>设置一个新的线程,它将暂停一段时间,然后中断主线程
>开始新的线程
>长时间睡眠(在主线程中)
>当我们被打断时打印出一种诊断方法(再次,在主线程中)
主线程中的睡眠并不是绝对必要的,但这意味着主线程在被中断之前确实开始睡眠.
