看看，你能不能理解，动态的哦。记着在查看结果的时候拉动一下窗口这样才能看见全部结果。

方法类：

String y = "";
String r = "";

{
case 0:y="石头";
if(computerFist==0){r="和电脑出得一样";result=1;}

break;
}
return "你出的是："+y+",电脑出的是："+getComputerFist()+"。你"+r;
}
public int getResult() {
return result;
}
}

测试类：
package test;
import java.util.Scanner;
public class TestCaiQuan {

while(num>0)
{

System.out.println("请输入您要出的拳（0 石头）（1 剪刀）（2 布）");
System.out.println(cq.getResult(input.nextInt()));
if(cq.getResult()==0)lose+=1;
else if(cq.getResult()==1)draw+=1;
else if(cq.getResult()==2)win+=1;
else error+=1;
num--;
}
System.out.println("您共玩了"+times+"次，赢"+win+"次，输"+lose+"次，平"+draw+"次,错误输入"+error+"次");
System.out.println("您的胜率是："+Double.valueOf(win)/times*100+"%");
