}

package 多线程.线程间通信_生产者和消费者;

public class demo01 {
    public static void main(String[] args) {
        Phone phone =new Phone();

        Producer producer =new Producer(phone);
        Thread t1 =new Thread(producer);
        t1.start();

        Consumer consumer =new Consumer(phone);
        Thread t2 =new Thread(consumer);
        t2.start();
    }
}

结果：

洛基亚-----黑色
苹果-----金色
洛基亚-----黑色
苹果-----金色
洛基亚-----黑色
