   Short sh = 1;
   s = s + sh;

   // create a new scanner with the specified String Object
   Scanner scanner = new Scanner(s);

   // use US locale in order to be able to identify shorts in a string
   scanner.useLocale(Locale.US);

   while (scanner.hasNext()) {
   // check if the scanner's next token is a short
   System.out.println("" + scanner.hasNextShort());

   // print what is scanned
