JAVA多线程之生产者和消费者模式

package com.test;

Box box=new Box();

new Thread(p1).start();
new Thread(p2).start();

}

}
//产品类
class ManTou {
private int id;

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

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

}

//容器类
class Box {
private int index = 0;
ManTou[] arr = new ManTou[8];

public synchronized void push(ManTou mt) {
	
	while (index == arr.length) {
		try {

//生产者
