package threadPage;//模拟火车站售票窗口，开启三个窗口售票，总数为100张class Window extends Thread{    static int ticket = 100;    static Object obj = new Object();    public void run() {        while (true) {            synchronized (obj) {                if (ticket > 0) {                    System.out.println(Thread.currentThread().getName()+"售票，票号：" + ticket--);                }            }        }    }}public class TestWindow {    public static void main(String[] args) {        Window w1 = new Window();        Window w2 = new Window();        Window w3 = new Window();        w1.start();        w2.start();        w3.start();    }}
