摘要： 如何应用合适的队列，这就是经验了。如何在队列里容纳多个线程，及多个线程处理同一个队列？

每个知识点都尽量涉及到，

但每种队列应用的场景都不一样的，

如何应用合适的队列，这就是经验了。

如何在队列里容纳多个线程，及多个线程处理同一个队列？

应该算是JAVA里比较深入的思考了。

producer

package demo.thread;

import java.util.Random;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.TransferQueue;

public class Producer implements Runnable {
	private final TransferQueue<String> queue;
	public Producer(TransferQueue<String> queue) {
		this.queue = queue;
	}
	
	private String produce() {
		return "Your lucky number " + (new Random().nextInt(100));
	}
	@Override
	public void run() {
		// TODO Auto-generated method stub
		try {
			while (true) {
				if (queue.hasWaitingConsumer()) {
					queue.transfer(produce());
				}
				TimeUnit.SECONDS.sleep(1);
			}
		} catch (InterruptedException e){
			
		}
		
	}

}

consumer

package demo.thread;

import java.util.concurrent.TransferQueue;

public class Consumer implements Runnable{
	private final TransferQueue<String> queue;
	public Consumer(TransferQueue<String> queue) {
		this.queue = queue;
	}
	@Override
	public void run() {
		// TODO Auto-generated method stub
		try {
			System.out.println("Consumer " + Thread.currentThread().getName() + queue.take());
			
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
		
	}

}

main

package demo.thread;

import java.util.concurrent.LinkedTransferQueue;
import java.util.concurrent.TransferQueue;

public class ThreadMain {
	public static void main(String[] args) {
		TransferQueue<String> queue = new LinkedTransferQueue<String>();
		Thread producer = new Thread(new Producer(queue));
		producer.setDaemon(true);
		producer.start();
		
		for (int i = 0; i < 10; i++) {
			Thread consumer = new Thread(new Consumer(queue));
			consumer.setDaemon(true);
			consumer.start();
			try {
				Thread.sleep(1000L);
			} catch(InterruptedException e) {
				e.printStackTrace();
			}
		}
		
		
	}

}

output

Consumer Thread-1Your lucky number 33
Consumer Thread-2Your lucky number 51
Consumer Thread-3Your lucky number 8
Consumer Thread-4Your lucky number 35
Consumer Thread-5Your lucky number 29
Consumer Thread-6Your lucky number 8
Consumer Thread-7Your lucky number 46
Consumer Thread-8Your lucky number 20
Consumer Thread-9Your lucky number 15
Consumer Thread-10Your lucky number 67
