Java生产者消费者问题

Java写的著名的生产者消费者问题：这里先贴上代码，后面如果需要的话加上详解

package com.jarven.thread;

public class WoTo {
	private int id;

	public WoTo(int id) {
		this.id = id;
	}

	@Override
	public String toString() {
		return "Woto: " + id;
	}
	
}

package com.jarven.thread;

public class SyncStack {

	int index = 0;		//栈顶指针
	
	WoTo[] wtArr = new WoTo[6];
	
	//放入
	public synchronized void push(WoTo wt) {
		while(index >= wtArr.length) {
			try {
				this.wait();				//调用该方法的线程休止
			} catch(InterruptedException e) {
				e.printStackTrace();
			}
		}
		this.notify();
		wtArr[index] = wt;
		index++;
	}
	
	public synchronized WoTo pop() {
		while(index <= 0) {
			try {
				this.wait();
			} catch(InterruptedException e) {
				e.printStackTrace();
			}
		}
		this.notify();
		index--;
		return wtArr[index];
	}
	
}

package com.jarven.thread;

public class Consumer implements Runnable {
	
	SyncStack syncStack;

	public Consumer(SyncStack syncStack) {
		this.syncStack = syncStack;
	}
	
	@Override
	public void run() {
		for(int i=1; i<=20; i++) {
			WoTo wt = syncStack.pop();
			System.out.println("消费者消费---------------->" + wt);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
	

}

package com.jarven.thread;

public class Producer implements Runnable {
	
	private SyncStack syncStack;
	
	public Producer(SyncStack syncStack) {
		this.syncStack = syncStack;
	}

	@Override
	public void run() {
		for(int i=1; i<=20; i++) {
			WoTo wt = new WoTo(i);
			syncStack.push(wt);
			System.out.println("生产者生产---------------->" + wt);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
	
}

package com.jarven.thread;

public class ProducerAndConsumer {
	
	public static void main(String[] args) {
		SyncStack syncStack = new SyncStack();
		Consumer c = new Consumer(syncStack);
		Producer p = new Producer(syncStack);
	
		Thread consumerThread = new Thread(c, "Consumer");
		Thread producerThread = new Thread(p, "Producer");
		
		consumerThread.start();
		producerThread.start();
	}
