is there any other way to do this ?
i want to do by using charAt() function and by decreasing the ascii code by 2 .


Write a program to encode a message. The idea is to shift each letter of a alphabet (a to z) or numeric digit (0-9) by previous two places.

For example :
C to A, M to K ?. A to Y. Similarly 3 to 1, 7 to 5 ?. 1 to 8

thanks

Hi Friend,

Try the following code:

import java.util.*;
public class Encode {

public static void main(String[] args) {
StringBuffer output = new StringBuffer();
System.out.println("Enter string to encode:");
Scanner input = new Scanner(System.in);
String st = input.nextLine();
String s=st.replace(" ","");
for(int i=0;i<s.length();i++){
char c=s.charAt(i);
--c;
--c;
output.append(c);
}
String str=output.toString();
String restr=str.replace('?','Y').replace('`','z').replace('_','y').replace('@','Z').replace('.','8').replace('/','9');
System.out.println(restr);
}
}

Hope that it will be helpful for you.
Thanks
