本文深入探讨了在Java中处理InterruptedException的方法，特别关注了中断标志位的重要性。通过一个具体示例，展示了如何在捕获异常后检查并重新设置中断状态，确保线程能够正确响应中断请求。

/**
 * 抛出InterruptedException异常的时候，要注意中断标志位

public class HasInterruptException {
    private static class UseThread extends Thread{
        public UseThread(String name) {
            super(name);
        }

        @Override
        public void run() {
            String threadName = Thread.currentThread().getName();
            while(!isInterrupted()) {
                try {
                    Thread.sleep(300);
                } catch (InterruptedException e) {
                    System.out.println(threadName + " catch InterruptedException interruptFlag is " + isInterrupted());
                    interrupt();
                }
                System.out.println(threadName);
            }
            System.out.println(threadName + " interruptFlag is " + isInterrupted());
        }
    }

    public static void main(String[] args) throws InterruptedException {
        Thread endThread = new UseThread("HasInterruptEx");
        endThread.start();
        Thread.sleep(1000);
        endThread.interrupt();
    }
}
