             */
            printStream.printf("i = %d and k = %f", intValue, doubleValue);
            Date date = new Date();
            System.out.println();
            /*
             * Prints an object.
             */
            printStream.print(date);

        }
        finally
        {
            if (printStream != null)
            {
                printStream.close();
