如何把字元轉換成數值

Mar 21st 2015, 18:57

package jk;

import java.io.*;

class io

{

public static void main(String args[])throws Exception

{

String EX;
int GG;
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
GG=Integer.parseInt(in.readLine());
GG=96+GG;

System.out.println ((char)GG);
}
}

這個比如在鍵盤上輸入1 就會輸出a 26就是z

我想問一下要怎樣寫可以反過來變成鍵盤輸入a 輸出是1
