class TicketSystem
{
public static void main(String[] args)
{
SellThread st=new SellThread();
new Thread(st).start();
new Thread(st).start();
new Thread(st).start();
new Thread(st).start();
}
}
class SellThread implements Runnable
{
int tickets=100;
public void run()
{
while(true)
{
if(tickets>0)
{
System.out.println(Thread.currentThread().getName()+"sell ticket:"+tickets);
tickets--;
}
}
}
}
孙老师的tickets是按顺序打印出来的，为什么我的却不是呢？程序都一样啊，是不是跟操作系统有关？谢谢
谢谢你，可是在您的结果中从第13行有一部分是：
Thread-0sell ticket:88
Thread-1sell ticket:98
Thread-0sell ticket:87
Thread-0sell ticket:85
Thread-1sell ticket:86
Thread-0sell ticket:84
Thread-3sell ticket:85
Thread-3sell ticket:81
我的结果也是类似的问题，您看这是为什么呢？谢谢

我测试了你的代码，是按顺序的啊。。
