public static boolean isInteger(String s, int radix) {
    Scanner sc = new Scanner(s.trim());
    if (!sc.hasNextInt(radix)) {
        return false;
    }/*from w  w w.  jav  a  2 s.c  om*/
    // we know it starts with a valid int, now make sure
    // there's nothing left!
    sc.nextInt(radix);
