1. SaleTicket st=new SaleTicket();
   
2. new Thread(st).start();
   
3. new Thread(st).start();
   
4. new Thread(st).start();
   
5. new Thread(st).start();

1. new Thread(new SaleTicket()).start();
   
2. new Thread(new SaleTicket()).start();
   
3. new Thread(new SaleTicket()).start();
   
4. new Thread(new SaleTicket()).start();

这两个有什么区别？

1. SaleTicket st=new SaleTicket();
   
2. new Thread(st).start();
   
3. new Thread(st).start();
