正确处理InterruptException

/**
* interrupt()方法、isInterrupted()方法、interrupted()方法
*/
public class Interrupt {
    public static void main(String[] args) throws Exception {
        Thread t = new Thread(new Worker());
        t.start();

        Thread.sleep(100);
        t.interrupt();

        System.out.println("Main thread stopped.");
    }

    /**
     * 抛出一次InterruptedException异常后JVm会把线程的中断状态清除掉interrupt的状态设置为false

                Thread.sleep(200);

                System.out.println("清除线程的中断状态interrupted();  Worker IsInterrupted--------: " +
                        Thread.currentThread().isInterrupted());

当线程处于阻塞状态的时候，如果这是被interrupt，会报InterruptException 错误，但是只是设置一个被打断的标志，不会正在的打断状态，所以要正确的处理exception，要加上Thread.currentThread().interrupt()方法，来中断线程
