Both problems would be avoided by using charAt() rather than substring(). Still not as fast as the straight arithmetic shown above. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Cast it with the offset added. int i = 0; char ch = (char)(i+97); Wrap in a try catch block if desired.

Oh, come on.
String letterAt(int i) {
return "abcdefghijklmnopqrstuvwxyz".substring(i, i + 1);
}
Fast, portable, simple.

Alternatively, you can add the ASCII offset to the integer, then get the char that evaluates to that ASCII code. I think its 32, but you'll need to check for sure.
