This is what I came up with.  Whether it's really better or not I think 
depends on your requirements.  Lightly tested.


    public static int test3( InputStream ins )
            throws MyEndOfInputException
    {
       Scanner scanner = new Scanner( ins );
       while( scanner.hasNext() ) {
          if( scanner.hasNextInt() )
             return scanner.nextInt();
           else
             scanner.next();
       }
       throw new MyEndOfInputException();
    }
}

class MyUtilsException extends Exception
{
}

class MyEndOfInputException extends MyUtilsException
{
}
