阻塞队列实现生产者-消费者模式

Posted 2022-11-01 胖子爱你520

public class Test 
  private int queueSize = 10;
  private ArrayBlockingQueue<Integer> queue = new ArrayBlockingQueue<>(queueSize);

  public static void main(String[] args) 
    Test test = new Test();
    Producer producer = test.new Producer();
    Consumer consumer = test.new Consumer();
    producer.start();
    consumer.start();
  

  class Consumer extends Thread 
    @Override
    public void run() 
      while (true) 
        try 
          queue.take();
          System.out.println("Consumer : queue.size = " + queue.size());
         catch (InterruptedException e) 

        
      
    
  

  class Producer extends Thread 
    @Override
    public void run() 
      while (true) 
        try 
          queue.put(1);
          System.out.println("Producer : queue.size = " + queue.size());
         catch (InterruptedException e) 

        
      
    
  

使用阻塞队列无需单独考虑同步和线程间通信的问题，实现起来很简单
