Interrupt notes

static void main public (String [] args) { 
        the Thread the Thread new new T = (the Runnable new new () { 
            @Override 
            public void RUN () { 
                the try { 
                    System.out.println ( "the begin SLEEP"); 
//Thread.interrupted ( ) clears the interrupt flag is false, System.out.println (Thread.interrupted ()); 
// If you call interrupt threads blocked on yet () will give the thread interrupt flag is set to true, then the call to throw immediately InterruptedException thrown when a blocking method.

                    Thread.sleep(2000);
                    System.out.println("after throwing...");
                } catch (InterruptedException e) {
                    System.out.println("after catching...");
                }
                System.out.println("exit run()...");
            }
        });
        t.start();
        try {
            TimeUnit.MILLISECONDS.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("t.interrupt() go");
        t.interrupt();
        System.out.println("t.interrupt() end");
    }

结果：

1：begin sleep
2：t.interrupt() go
3：t.interrupt() end
4：after catching...
5：exit run()...

Because it is two threads, 3,4,5 random order

 

　　The above is interrupted sleep, the next interrupt wait

　　　　　　　　　　　　// the wait () method when the block must be in sync or synchronization method, and lock objects and call the object to be consistent, otherwise it will throw a runtime exception java.lang.IllegalMonitorStateException

                    synchronized (Thread.currentThread()){
                        Thread.currentThread().wait();
                    }
                    System.out.println("after throwing...");

　　结果：

1：begin wait
2：t.interrupt() go
3：t.interrupt() end
4：after catching...
5：exit run()...

　　In addition interrup () method can not be interrupted IO blocking and blocking mutex lock, then there are two solutions

　　1: Close competitive resources, such as: When IO blocked, closed blocking flow, or use nio, nio provide a more humane interrupt response, the blocked channel will automatically respond to interrupts.

　　2: Use of ReentrantLock lockInterruptibly in () method to get the lock, then locks the mutex may correspond interrup () method.
