java多线程实现同步锁卖票实战项目

public class Ticket implements Runnable{
    int tickets=20;//总共20张票
    @Override
    public  void run() {
        while (tickets>0) {
            synchronized (this) {
                if(tickets>0) {
                    //售票
                    try {
                        System.out.println(Thread.currentThread().getName()+"正在售票");
                        Thread.sleep(200);//模拟售票操作时间
                        tickets--;//完成售票
                        System.out.println(Thread.currentThread().getName()+"售票完成,"+"剩余"+tickets+"张票");
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }
    }
}

public class Test {
    public static void main(String[] args) {
        Ticket ticket = new Ticket();
