线程通信生产者消费者阻塞队列版

一个初始值为0的变量，两个线程对其交替操作，一个加1，一个减1，循环5次。

代码：

public class ProduceConsumer_BlockingQueue {

    public static void main(String[] args) {
        MyResource myResource = new MyResource(new ArrayBlockingQueue<String>(10));
        new Thread(() -> {
            System.out.println(Thread.currentThread().getName() + "\t" + "生产线程开始了");
            try {
                myResource.myProd();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }, "t1").start();

        new Thread(() -> {
            System.out.println(Thread.currentThread().getName() + "\t" + "消费线程开始了");
            System.out.println();
            System.out.println();
            try {
                myResource.myConsumer();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }, "t2").start();

        try {
            TimeUnit.SECONDS.sleep(5);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println();
        System.out.println();
        System.out.println("5秒钟时间到了，大老板main线程叫停，活动结束");
        myResource.stop();
    }

}

class MyResource {
    private volatile boolean flag = true;
    private AtomicInteger atomicInteger = new AtomicInteger();

    private BlockingQueue blockingQueue = null;

    public MyResource(BlockingQueue blockingQueue) {
        this.blockingQueue = blockingQueue;
    }

    public void myProd() throws InterruptedException {
        String data=null;
        boolean returnValue;
        while (flag) {
            data = atomicInteger.incrementAndGet()+"";
            returnValue = blockingQueue.offer(data + "", 2L, TimeUnit.SECONDS);
            if (returnValue) {
                System.out.println(Thread.currentThread().getName() + "\t 插入队列" + data + "成功");
            } else {
                System.out.println(Thread.currentThread().getName() + "\t 插入队列" + data + "失败");
            }
            TimeUnit.SECONDS.sleep(1);
        }
        System.out.println(Thread.currentThread().getName() + "\t 大老板叫停了，表示flage=false,生产动作结束");
    }

    public void myConsumer() throws InterruptedException {
        String s =null;
        while (flag) {
            s = (String) blockingQueue.poll(2L, TimeUnit.SECONDS);
            if (null == s || s.equalsIgnoreCase("")) {
                flag = false;
                System.out.println(Thread.currentThread().getName() + "\t 超过2秒钟没有取到数据，消费退出");
                return;
            }
            System.out.println(Thread.currentThread().getName() + "\t" + "消费队列" + s + "成功");
        }
        System.out.println(Thread.currentThread().getName() + "\t 消费队列听了");
    }

    public void stop() {
        flag = false;
    }
}

结果：
