    测试类:

    package java12;

    public class renjicaiquan3 {
    public static void main(String[] args) {
      renjicaiquan2 play=new renjicaiquan2();                  //创建游戏类的对象
      play.process();                //调用游戏类的游戏进程方法
      play.showResult();               //调用游戏类的结算方法
      }
    }
