生产者消费者简单模拟

 前几天写的，简单模拟了生产者消费者，不是很完美，大家多提意见

/**

* 生产者和消费者由商店管理

*/

class Shop extends Thread {

int product;

boolean empty = true;

//放入商品

public synchronized void put(int pro) {

while (empty == false) {

try {

wait();

} catch (Exception e) {

}

}

product = pro;

empty = false;

System.out.println("put the: " + product);

notify();

}

//取走商品

public synchronized int get() {

while (empty == true) {

try {

wait();

} catch (Exception e) {

}

}

empty = true;

System.out.println("get the: " + product);

notify();

return product;

}

}

/**

* 生产者

*/

class Producter extends Thread {

int product;

Shop shop;

public Producter(Shop s) {

product = 0;

shop = s;

}

public void run() {

for (int i = 0; i < 10; i++) {

shop.put(i);

}

}

}

/**

* 消费者

*/

class Consumer extends Thread {

int product;

Shop shop;

public Consumer(Shop s) {

product = 0;

shop = s;

}

public void run() {

for (int i = 0; i < 10; i++) {

product = shop.get();

}

}

}

public class ProducerConsuner {

public static void main(String args[]) {

Shop sh = new Shop();

Producter p = new Producter(sh);

Consumer c = new Consumer(sh);

p.start();

c.start();

}

}
