为什么最后报错显示 shiJi cannot be resolved to a variable 。

Question

package 临时; import java.util.Scanner; public class xioafei { public static void main(String[] args){ Scanner input=new Scanner(System.in); System.out.print("请输入您的消费总额："); int zongE=input.nextInt(); System.out.println();         System.out.println("请出示您的会员卡：");         int huiYuan=input.nextInt();         if(huiYuan==1)         {          double shiJi=zongE*0.6;          if(huiYuan==2)          {               shiJi=zongE*0.7;          if(huiYuan==3)          {            shiJi=zongE*0.8;          if(huiYuan==4)          {           shiJi=zongE*0.85;          if(huiYuan==5)          {            shiJi=zongE*0.9;          if(huiYuan==6)          {           shiJi=zongE*0.95;          }          }          }          }          }         }         double zheKou=zongE-shiJi;         System.out.println("消费总金额为"+zongE+"元，实际支付"+shiJi+"元，折后为"+zheKou+"元。"); } }

Answer 1

虽然这是一个java题，我就斗胆回答一下，

double shiJi=zongE*0.6;  应该放到 if的最外面，应该是变量作用域的问题
