BlockingQueue

BlockingQueue实现的生产者消费者模式：10个线程生产 1个线程消费

package com.jerry.concurrency; import java.util.concurrent.BlockingQueue; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.LinkedBlockingQueue; public class TestBlockingQueue { public static void main(String[] args) { ExecutorService 生产者 =Executors.newCachedThreadPool(); ExecutorService 消费者=Executors.newCachedThreadPool(); final BlockingQueue<String> 队列 = new LinkedBlockingQueue<String>(3); for(int i=0;i<=10;i++){ 生产者.submit(new Runnable() { @Override public void run() { Double d = Math.random()*1000; try { 队列.put(d.toString()); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("线程"+Thread.currentThread().getName()+"放入了："+d); } }); } 消费者.submit(new Runnable() { @Override public void run() { try { while (true) { Thread.sleep((int) (Math.random() * 1000)); if(队列.isEmpty()) break; String str = 队列.take(); System.out.println("线程"+Thread.currentThread().getName()+"取出了："+str); } } catch (Exception e) { e.printStackTrace(); } } }); } }
