java 5并发中的阻塞队列ArrayBlockingQueue的使用以及案例实现

public class BlockingQueueTest
{
public static void main(String[] args)
{
//创建一个包含三个元素的阻塞队列
final BlockingQueue<Integer> queue = new ArrayBlockingQueue<Integer>(3);
for (int i = 0; i < 2; i++)
{
new Thread(new Runnable()
{
@Override
public void run()
{
while(true){
try
{
Thread.sleep(1000);
System.out.println("线程"+Thread.currentThread().getName()+" 准备放数据了");
queue.put(new Random().nextInt(100));
System.out.println("线程"+Thread.currentThread().getName()+" 已经放完数据了,目前队列有"+queue.size()+"个数据");
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}).start();

}

new Thread(new Runnable()
{
@Override
public void run()
{
while(true){
try
{
//将此处的睡眠时间改为200和2000 分别观察结果
Thread.sleep(2000);
System.out.println("线程"+Thread.currentThread().getName()+" 准备取数据了");
queue.take();
System.out.println("线程"+Thread.currentThread().getName()+" 已经取完数据了,目前队列有"+queue.size()+"个数据");
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}).start();
}
}
