How can I convert a to String using
DateTimeFormatter dateTimeFormatter = ("yyyy-MM-dd'T'HH:mm:ss")
The Date object which i get is passed
DateTime now = new DateTime(date);

If you are using Java 8, you should not use in the first place (unless you receive the Date object from a library that you have no control over).
In any case, you can convert a Date to a using:
Date date = ...;
Instant instant = ();
Since you are only interested in the date and time, without timezone information (I assume everything is UTC), you can convert that instant to a LocalDateTime object:
LocalDateTime ldt = ().toLocalDateTime();
Finally you can print it with:
DateTimeFormatter fmt = ("yyyy-MM-dd'T'HH:mm:ss");
((fmt));
((DateTimeFormatter.ISO_LOCAL_DATE_TIME));
Note that if you don't provide a formatter, calling gives output in standard ISO 8601 format (including milliseconds) - that may be acceptable for you.
