-类里面的元素需要实现*java.util.concurrent.Delay*接口。下面是Delay接口的示例代码：
+DelayQueue class implements the BlockingQueue interface. Read the BlockingQueue text for more information about the interface.

 The value returned by the getDelay() method should be the delay remaining before this element can be released. If 0 or a negative value is returned, the delay will be considered expired, and the element released at the next take() etc. call on the DelayQueue.
 
 The TimeUnit instance passed to the getDelay() method is an Enum that tells which time unit the delay should be returned in. The TimeUnit enum can take these values:
