练习3个窗口同时售票100张

使用继承 Thread 方式

package com.klvchen.java;
/**

 *
 * 例子：创建三个窗口卖票，总票为 100 张
 * 存在线程安全问题，待解决
 */
class Window extends Thread{
    private static int ticket = 100;
    @Override
    public void run(){
        while (true){
            if (ticket > 0){
                System.out.println(getName() + ": 卖票, 票号为: " + ticket);
                ticket--;
            }else {
                break;
            }
        }
    }
}
public class WindowTest {
    public static void main(String[] args){
        Window t1 = new Window();
        Window t2 = new Window();
        Window t3 = new Window();
        t1.setName("窗口1");
        t2.setName("窗口2");
        t3.setName("窗口3");
        t1.start();
        t2.start();
        t3.start();
    }
}

实现Runnable接口的方式

package com.klvchen.java;
/**

 * 例子:创建三个窗口卖票，总票数为100张.使用实现Runnable接口的方式
 * 存在线程的安全问题,待解决。

class Windows1 implements Runnable{
    private int ticket = 100;
    @Override
    public void run() {
        while (true){
            if (ticket > 0){
                System.out.println(Thread.currentThread().getName() + "卖票,票号为：" + ticket);
                ticket--;
            }else {
                break;
            }
        }
    }
}
public class WindowTest1 {
    public static void main(String[] args){
        Windows1 w = new Windows1();
        Thread t1 = new Thread(w);
        Thread t2 = new Thread(w);
        Thread t3 = new Thread(w);
        t1.setName("窗口1");
        t2.setName("窗口2");
        t3.setName("窗口3");
        t1.start();
        t2.start();
        t3.start();
    }
}
