第九周课程总结&实验报告

实验任务详情：

完成火车站售票程序的模拟。
要求：
（1）总票数1000张；
（2）10个窗口同时开始卖票；
（3）卖票过程延时1秒钟；
（4）不能出现一票多卖或卖出负数号票的情况。

实验源码

class test implements Runnable {
    static int ticket = 999;
    public void run() {
        for (int i = 0; i < 1000; i++)
            synchronized (this) {
                if (ticket >= 0) {
                    if (ticket == 0) {
                        System.out.println(Thread.currentThread().getName() + "票已售罄");
                        break;}
                    else {
                        try {
                            Thread.sleep(1000);
                        }
                        catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        System.out.println(Thread.currentThread().getName() + "卖出一张票" + " " + "所剩余票为：" + ticket);
                        ticket--;
                    }
                }
            }
    }
}

public class cao {
    public static void main(String args[]) {
        test t = new test();
        Thread th1 = new Thread(t, "窗口1");
        Thread th2 = new Thread(t, "窗口2");
        Thread th3 = new Thread(t, "窗口3");
        Thread th4 = new Thread(t, "窗口4");
        Thread th5 = new Thread(t, "窗口5");
        Thread th6 = new Thread(t, "窗口6");
        Thread th7 = new Thread(t, "窗口7");
        Thread th8 = new Thread(t, "窗口8");
        Thread th9 = new Thread(t, "窗口9");
        Thread th10 = new Thread(t, "窗口10");

        th1.start();
        th2.start();
        th3.start();
        th4.start();
        th5.start();
        th6.start();
        th7.start();
        th8.start();
        th9.start();
