Java基础 等待唤醒机制——生产者代码实现

package pojo.xc01;

public class Cook extends Thread{
    @Override
    public void run() {
        while (true) {
            synchronized (Desk.lock) {
                if (Desk.count == 0) break;

                if (Desk.foodFlog == 1) {//桌子上有食物，就等待
                    try {
                        Desk.lock.wait();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                } else { //没有食物，就制作食物
                    Desk.foodFlog = 1;
                    System.out.println("做好了");
                    Desk.lock.notifyAll();//唤醒消费者开吃
                }
            }
        }
    }
}
