我想创建一种类似于生产者/消费者的线程应用程序，但我不确定在它们之间实现队列的最佳方法是什么。
所以我想到了两个想法（可能都是错误的）。我想知道哪一个更好，如果它们都不好，那么最佳的队列实现方法是什么。这些示例中，我主要关心队列的实现方式。我正在扩展一种队列类，它是内部类并且是线程安全的。下面是两个示例，每个示例有4个类。
主类 -

主类 -
public class SomeApp
{
private Consumer consumer;
private Producer producer;
public static void main (String args[])
{
consumer = new Consumer();
producer = new Producer();
}
}
消费者类 -
public class Consumer implements Runnable
{
public Consumer()
{
Thread consumer = new Thread(this);
consumer.start();
}
public void run()
{
while(true)
{
//get an object off the queue
Object object = QueueHandler.dequeue();
//do some stuff with the object
}
}
}
生产者类 -
public class Producer implements Runnable
{
public Producer()
{
Thread producer = new Thread(this);
producer.start();
}
public void run()
{
while(true)
{
//add to the queue some sort of unique object
QueueHandler.enqueue(new Object());
}
}
}
队列类 -
public class QueueHandler
{
//This Queue class is a thread safe (written in house) class
public static Queue<Object> readQ = new Queue<Object>(100);
public static void enqueue(Object object)
{
//do some stuff
readQ.add(object);
}
public static Object dequeue()
{
//do some stuff
return readQ.get();
}
}
或者
主类-
public class SomeApp
{
Queue<Object> readQ;
private Consumer consumer;
private Producer producer;
public static void main (String args[])
{
readQ = new Queue<Object>(100);
consumer = new Consumer(readQ);
producer = new Producer(readQ);
}
}
消费者类 -
public class Consumer implements Runnable
{
Queue<Object> queue;
public Consumer(Queue<Object> readQ)
{
queue = readQ;
Thread consumer = new Thread(this);
consumer.start();
}
public void run()
{
while(true)
{
//get an object off the queue
Object object = queue.dequeue();
//do some stuff with the object
}
}
}
生产者类 -
public class Producer implements Runnable
{
Queue<Object> queue;
public Producer(Queue<Object> readQ)
{
queue = readQ;
Thread producer = new Thread(this);
producer.start();
}
public void run()
{
while(true)
{
//add to the queue some sort of unique object
queue.enqueue(new Object());
}
}
}
队列类 -
//the extended Queue class is a thread safe (written in house) class
public class QueueHandler extends Queue<Object>
{
public QueueHandler(int size)
{
super(size); //All I'm thinking about now is McDonalds.
}
public void enqueue(Object object)
{
//do some stuff
readQ.add();
}
public Object dequeue()
{
//do some stuff
return readQ.get();
}
}
开始吧！
