Runnable接口创建多线程例子

哈尔滨火车站下面有三个火车票代售点，假如哈尔滨到北京的火车票总共是200张，如何用程序来实现三个售票点同时卖票的功能。

public class Ticket implements Runnable{ private int tickets = 200; //200张火车票 boolean flag = true; private synchronized void sale() { if (tickets <= 0) { flag = false; return; } tickets--; System.out.print(Thread.currentThread().getName() + " sales a ticket, "); if (tickets > 1) System.out.println("there are " + tickets + " tickets"); else System.out.println("there is " + tickets + " ticket"); } public void run() { while(flag) { sale(); try { Thread.sleep(100); } catch (InterruptedException e){ e.printStackTrace(); } } }}public class Main { public static void main(String[] args) { Ticket t = new Ticket(); Thread th1 = new Thread(t,"system 1"); Thread th2 = new Thread(t,"system 2"); Thread th3 = new Thread(t,"system 3"); th1.start(); th2.start(); th3.start(); }}
