Date Function is trimming seconds where seconds is 00

OffsetDateTime odtB = OffsetDateTime.parse("2019-02-02T13:55:00Z");
odtB.toString()

prints 2019-02-02T13:55 as output. As because of this my conversion function is throwing error!!

SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM\''YY HH:mm aa");
String parsedDate = odtB.format(otdB);

How to stop OffsetDateTime or anyOther Java DateTime class from trimming seconds off when seconds are 00??

In java8, you do not need SimpleDateFormat any more, it's troublesome.

I suggest to use ISO_OFFSET_DATE_TIME:

The ISO date-time formatter that formats or parses a date-time with an offset, such as '2011-12-03T10:15:30+01:00'.

Example:

import java.util.*;
import java.time.*;
import java.time.format.*;

public class HelloWorld{

     public static void main(String []args){
        OffsetDateTime odtB = OffsetDateTime.parse("2019-02-02T13:55:00Z");
        DateTimeFormatter f = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
        System.out.print(f.format(odtB)); // 2019-02-02T13:55:00Z
     }
}
