4. PriorityBlockingQueue 基于优先级的阻塞队列(优先级的判断通过构造函数传入的Compator对象来决定),但需要注意的是PriorityBlockingQueue并不会阻塞数据生产者,而只会在没有可消费的数据时,阻塞数据的消费者。因此使用的时候要特别注意,生产者生产数据的速度绝对不能快于消费者消费数据的速度, 否则时间一长,会最终耗...

The poll() method of the Queue interface returns the object at the top of the current queue and removes it. If the queue is empty this method returns null. Example Live Demo import java.util.Iterator; import java.util.LinkedList; import java.util.Queue; public class QueueExample { p...
DelayQueue是JDK1.5时,随着J.U.C包一起引入的一种阻塞队列,它实现了BlockingQueue接口,底层基于已有的PriorityBlockingQueue实现 DelayQueue是阻塞队列中非常有用的一种队列,经常被用于缓存或定时任务等的设计,例如: a) 关闭空闲连接。服务器中,有很多客户端的连接,空闲一段时间之后需要关闭之。
