            = LocalDateTime
                  .parse("2018-11-03T12:45:30");
  
        // Prints the date
        System.out.println("Date 2: " + dt2);
  
        // Compares the date
        System.out.println("Is Date 1 "
                           + "equal to Date 2: "
                           + dt2.equals(dt1));
    }
}
