（仿牛客社区项目）Java开发笔记5.1：阻塞队列

阻塞队列

1.添加阻塞队列测试方法

在test包中添加BlockingQueueTests类，书写阻塞队列测试方法。

package com.gerrard.community;

import java.util.Random;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;

public class BlockingQueueTests {
    public static void main(String[] args) {
        BlockingQueue queue = new ArrayBlockingQueue(10);
        new Thread(new Producer(queue)).start();
        new Thread(new Consumer(queue)).start();
        new Thread(new Consumer(queue)).start();
        new Thread(new Consumer(queue)).start();
    }
}
class Producer implements Runnable{
    private BlockingQueue<Integer> queue;

    public Producer(BlockingQueue<Integer> queue) {
        this.queue = queue;
    }
    @Override
    public void run(){
        try{
            for(int i=0;i<100;i++){
                Thread.sleep(20);
                queue.put(i);
                System.out.println(Thread.currentThread().getName()+"生产："+queue.size());
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

class Consumer implements Runnable{
    private BlockingQueue<Integer> queue;

    public Consumer(BlockingQueue<Integer> queue) {
        this.queue = queue;
    }

    @Override
    public void run() {
        try {
            while (true){
                Thread.sleep(new Random().nextInt(1000));
                queue.take();
                System.out.println(Thread.currentThread().getName()+"消费："+queue.size());
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
