java的各个队列之间的联系和区别是什么
java的各个并发队列之间的联系和区别
java.util.concurrent是在并发编程中很常用的实用工具类
ArrayBlockingQueue, DelayQueue, LinkedBlockingDeque, LinkedBlockingQueue, PriorityBlockingQueue, SynchronousQueue
下面是代码例子
/** * */ package concurrent; import java.util.Random; import java.util.concurrent.BlockingQueue; /** * @author think * */ class Producer implements Runnable { private final BlockingQueue<Integer> queue; Producer(BlockingQueue<Integer> q) { queue = q; } public void run() { try { while (true) { queue.put(produce()); } } catch (InterruptedException ex) { System.out.println(ex); } } Integer produce() { Random random = new Random(); return random.nextInt(); } }
/** * */ package concurrent; import java.util.concurrent.BlockingQueue; /** * @author think * */ class Consumer implements Runnable { private final BlockingQueue<Integer> queue; Consumer(BlockingQueue<Integer> q) { queue = q; } public void run() { try { while (true) { consume(queue.take()); } } catch (InterruptedException ex) { System.out.println(ex); } } void consume(Integer x) { System.out.println(x); } }
/** * */ package concurrent; import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.BlockingQueue; /** * @author think * */ class Setup { public static void main(String[] args) { BlockingQueue<Integer> q = new ArrayBlockingQueue<Integer>(100); Producer p = new Producer(q); Consumer c1 = new Consumer(q); Consumer c2 = new Consumer(q); new Thread(p).start(); new Thread(c1).start(); new Thread(c2).start(); } }
ArrayBlockingQueue 一个由数组支持的有界阻塞队列
DelayQueue Delayed 元素的一个无界阻塞队列,只有在延迟期满时才能从中提取元素
LinkedBlockingDeque 一个基于已链接节点的、任选范围的阻塞双端队列。
LinkedBlockingQueue 一个基于已链接节点的、范围任意的 blocking queue。
PriorityBlockingQueue 一个无界阻塞队列,它使用与类 PriorityQueue
相同的顺序规则,并且提供了阻塞获取操作。
SynchronousQueue 一种阻塞队列,其中每个插入操作必须等待另一个线程的对应移除操作 ,反之亦然。
