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！！
