        System.out.println(dt1);
  
        // Parses the date
        ChronoLocalDateTime dt2
            = LocalDateTime.parse("2016-12-04T12:45:30");
  
        // Prints the date
        System.out.println(dt2);
  
        // Compares both dates
        System.out.println(dt1.isEqual(dt2));
    }
