本文介绍了一个基于生产者消费者模式的馒头生产线模拟，通过两个线程分别模拟生产者和消费者角色，实现馒头的生产与消费过程。生产者线程随机生成馒头，并将馒头放入阻塞队列中；消费者线程从队列中取出馒头进行消费，并实时更新已消费馒头的数量和队列中的剩余馒头数量。

final BlockingQueue<String> queue=new ArrayBlockingQueue<String>(5);

public static void main(String[] args) {

     xiaofeizhe xiaofeizhe=new xiaofeizhe();
     xiaofeizhe.begin();

}

public void begin() {

  Thread t1=new Thread(new chihuo());
  t1.start();

  Thread t2=new Thread(new laoban());
  t2.start();

      Thread.sleep((long)(Math.random()*1000));
      queue.put("馒头"+(++count));
      System.out.println("生产一个馒头，总共生产了"+count+"个馒头"+"还有"+queue.size()+"个");
