如何在java中打印字母表的镜像值？

public class Alphamirror {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner sc=new Scanner(System.in);
        String s1=sc.next();
        String s2="";
        char c;
        int i;
        for(i=0;i<s1.length();i++)
            if(s1.charAt(i)<'m')
                s2=s1.charAt(i)+
            else if(||s1.charAt(i)>'z')
    }

你可以找出镜像字母表的索引并打印出来。请参阅下面的代码..

public static void main (String[] args) throws java.lang.Exception
   {
    // your code goes here
    Scanner sc=new Scanner(System.in);
    String s1=sc.next();

    for(int i = 0; i < s1.length(); i++) {
        int index = 'z' - s1.charAt(i);
        System.out.print((char)('a' + index));  
    }
}
