不知道哪里的毛病，关于WOW密保卡读取密保卡卡码的小程序~~~

Question

package wow;import javax.swing.JOptionPane;public class WowInput {  public static void main(String[] args) { String input;
String [][]card ={
          {"","26","23","01","67","84","67","78","99","21","73"},
          {"","95","57","14","24","73","92","91","00","54","75"},
          {"","24","65","05","68","17","17","00","68","26","63"},
          {"","68","88","51","30","89","39","05","90","62","28"},
          {"","33","31","83","76","42","11","16","08","89","56"},
          {"","77","22","51","23","17","02","78","99","90","11"},
          {"","12","01","31","44","51","67","72","82","99","10"},
          {"","12","23","44","15","78","00","02","04","54","19"}
                                                                 };

int xiabiaoshu=0;
String []Z={"z","a","b","c","d","e","f","g","h"};
    int [] az = {1,2,3,4,5,6,7,8};
do{


String zimu =JOptionPane.showInputDialog("请输入密保查询号之字母部分(输入范围为：a-h)");

String s =JOptionPane.showInputDialog("请输入密保查询号之数字部分（输入范围为：1-10）");
int shuzi =Integer.parseInt(s);

//建立一个字符数组，按顺序录入A到H，之后返回对应的下标，用字母Z占0下标。

    for(int shu : az)//这就是问题所在了。
    if (zimu == Z[shu])
    {xiabiaoshu =shu;
                         

}
System.out.println(card[xiabiaoshu][shuzi]);
input=JOptionPane.showInputDialog("继续使用吗？（y/n）");}
while(input.equals("y"));
    }

}我按字母读取的卡号只能读取第一行比如输入a,1的值没有问题。但是当我输入其它字母比如b c d等等却仍然是a组里的值，读取不到其它组的值。希望有热心人能帮我，看看。我还试过把字母转换为数组下标数的写进另一个类，然后调用方法得到返回数。
我刚学JAVA的，没什么深度理解，写的东西可能让大家看着头疼，但是希望大家不要笑话我，不吝赐教，谢谢了！！

改了改，供楼主参考import javax.swing.JOptionPane; public class WowInput {  public static void main(String[] args) {  String input; 
String [][]card ={ 
          {"26","23","01","67","84","67","78","99","21","73"}, 
          {"95","57","14","24","73","92","91","00","54","75"}, 
          {"24","65","05","68","17","17","00","68","26","63"}, 
          {"68","88","51","30","89","39","05","90","62","28"}, 
          {"33","31","83","76","42","11","16","08","89","56"}, 
          {"77","22","51","23","17","02","78","99","90","11"}, 
          {"12","01","31","44","51","67","72","82","99","10"}, 
          {"12","23","44","15","78","00","02","04","54","19"} 
                                                                 };  do{ 
int zimu =JOptionPane.showInputDialog("请输入密保查询号之字母部分(输入范围为：a-h)").toLowerCase().charAt(0)-97 ; 
String s =JOptionPane.showInputDialog("请输入密保查询号之数字部分（输入范围为：1-10）"); 
int shuzi =Integer.parseInt(s);  System.out.println(card[shuzi-1][zimu]); 
input=JOptionPane.showInputDialog("继续使用吗？（y/n）");} 
while(input.equals("y")); 
   } }

Answer 2

Many Thx to John!!  谢谢你！！！我加班，回帖晚了 不好意思啊！！我现在就去试试！谢谢你给我的帮助！！！

Answer 3

我试过了，现在可以读取其它行了，但是我想用字母来控制数组的行数比如a,是第一行的数组，B是第二行，C是第三行...，然后数字来控制列的数值，比如A1，就是26，B1就是95，C1就是24。A2是23，B2是57~~Mr.John~~谢谢你的点播我现在去查API， int zimu =JOptionPane.showInputDialog("请输入密保查询号之字母部分(输入范围为：a-h)").toLowerCase().charAt(0)-97 ;  再次谢谢你~~

Answer 4

把 zimu 换了个位置，一切OK了~~！：）
