I don't know if this works, but...

private static String makeStr(int num) {
    return new String((char)('a' + num / 26)) + (char)('a' + num % 26);
}

Jimbo, that works, but with a little modification:

private static String makeStr(int num) {
    return String.valueOf((char)('a' + num / 26)) + (char)('a' + num % 26);
}

Not only is the following code simple, but it's also faster, since it creates only one String object:

private static String makeStr(int num) {
    return new String(new char[]{ (char)('a' + num / 26), (char)('a' + num % 26) });
}

I want my $1! :p
