/*  <- This character pair (a slash and an asterisk) starts a multiline
       comment.  The multiline comment ends when these characters
       are encountered in the opposite order, i.e., an asterisk 
       precedes a slash.

       NOTE: An alternative implementation of the main() method is
             the following:

   public static void main( String[] not_in_use )
   {
      Scanner keyboard = new Scanner( System.in ) ;

      print_sum( 555, 222 ) ;

      System.out.print( "\n As you can see, this program can print"
                     +  "\n the sum of two integers. Please, type in"
                     +  "\n the first integer: " ) ;

      int first_integer  =  keyboard.nextInt() ;

      System.out.print( "\n And now the second integer: " ) ;

      int second_integer  =  keyboard.nextInt() ;

      print_sum( first_integer, second_integer ) ;
   }
}
