ArrayBlockingQueue 实现线程同步效果例子

1.Bread 类：

package com.dada.concurrent;

public class Bread {
	
}

2.Producer类：

package com.dada.concurrent;

import java.util.concurrent.ArrayBlockingQueue;

public class Producer implements Runnable {
	private final ArrayBlockingQueue<Bread> queue;
	
	public Producer(ArrayBlockingQueue<Bread> queue) {
		this.queue = queue;
	}
	@Override
	public void run() {
		while(true) {
			produce();
		}
	}
	public void produce() {
		try{
			Bread bread = new Bread();
			queue.put(bread);
			System.out.println("Producer:"+bread);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
	}

}

3.Consumer类：

package com.dada.concurrent;

import java.util.concurrent.ArrayBlockingQueue;

public class Consumer implements Runnable {
	private final ArrayBlockingQueue<Bread> queue;
	
	public Consumer(ArrayBlockingQueue<Bread> queue) {
		this.queue = queue;
	}
	
	@Override
	public void run() {
		while(true) {
			try {
				consume();
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
	}

	public void consume() throws Exception {
		try{
			Bread bread = queue.take();
			System.out.println("Consumer:"+bread);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
}

4.Client类：

package com.dada.concurrent;

import java.util.concurrent.ArrayBlockingQueue;

public class Client {
	public static void main(String[] args) {
		new Thread(new Producer(queue)).start();
		new Thread(new Producer(queue)).start();
		new Thread(new Consumer(queue)).start();
		new Thread(new Consumer(queue)).start();
		new Thread(new Consumer(queue)).start();
	}
	
	private static int capacity  = 10;
	private static ArrayBlockingQueue<Bread> queue = new ArrayBlockingQueue<Bread>(capacity);
}
