In this article, we will learn how to convert OffsetDateTime in different formats using Java 1.8 version or in short how to convert OffsetDateTime into String-form
For String to an OffsetDateTime conversion, read Java 8 – How to convert String to OffsetDateTime ?
1. Convert OffsetDateTime in different formats :
- We can convert default ISO_OFFSET_DATE_TIME format (yyyy-MM-ddTHH:mm:ss.nnn+/-HH:mm) to any other formats using OffsetDateTime.format() method by passing DateTimeFormatter as argument with required pattern in String-form
- In below illustration, we are using 6 different custom formats as mentioned below,
- DateTimeFormatter.ofPattern(“dd-MM-yyyy HH:mm:ss.nnn XXX“)
- DateTimeFormatter.ofPattern(“dd-MM-yyyy hh:mm:ss.nnn a XXX“)
- DateTimeFormatter.ofPattern(“dd.MM.yyyy HH:mm:ss XXX“)
- DateTimeFormatter.ofPattern(“dd-MMM-yyyy hh:mm:ss a XXX“)
- DateTimeFormatter.ofPattern(“E dd/MMMM/yyyy HH:mm XXX“)
- DateTimeFormatter.ofPattern(“EEEE MMMM dd, yyyy hh:mm a XXX“)
- Note: If the specified custom format/pattern isn’t in correct form then DateTimeParseException is thrown
2. OffsetDateTime examples in different formats :
- OffsetDateTime to (dd-MM-yyyy HH:mm:ss.nnn XXX) format
- OffsetDateTime to (dd-MM-yyyy hh:mm:ss.nnn a XXX) format
- OffsetDateTime to (dd.MM.yyyy HH:mm:ss XXX) format
- OffsetDateTime to (dd-MMM-yyyy hh:mm:ss a XXX) format
- OffsetDateTime to (E dd/MMMM/yyyy HH:mm XXX) format
- OffsetDateTime to (EEEE MMMM dd, yyyy hh:mm a XXX) format
2.1 OffsetDateTime to (dd-MM-yyyy HH:mm:ss.nnn XXX) format :
- This example converts OffsetDateTime in default (yyyy-MM-ddTHH:mm:ss.nnn+/-HH:mm) format to (dd-MM-yyyy HH:mm:ss.nnn XXX) format
FormatOffsetDateTimeExample1.java
package in.bench.resources.java8.offsetdatetime.examples;
import java.time.OffsetDateTime;
import java.time.format.DateTimeFormatter;
public class FormatOffsetDateTimeExample1 {
public static void main(String[] args) {
// 1. get current system date/time with offset
OffsetDateTime offsetDateTime = OffsetDateTime.now();
System.out.println("Current System Date/time is :- \n"
+ offsetDateTime);
// 2. DateTimeFormatter
DateTimeFormatter dateTimeFormatter = DateTimeFormatter
.ofPattern("dd-MM-yyyy HH:mm:ss.nnn XXX");
// 3. OffsetDateTime to (dd-MM-yyyy HH:mm:ss.nnn XXX) format in String form
String str = offsetDateTime.format(dateTimeFormatter);
System.out.print("\nOffsetDateTime to (dd-MM-yyyy HH:mm:ss.nnn XXX) format :- \n"
+ str);
}
}

3. Throws DateTimeParseException for Invalid format :
- If the specified pattern/format is invalid then DateTimeParseException is thrown
- In the below illustration, small-letter ‘m‘ is used for Month which is wrong
- Date notation,
- Capital-letter ‘M‘ should be used for Month
- Small-letter ‘d‘ should be used for Day
- Small-letter ‘y‘ should be used for Year
- Time notation,
- Capital-letter ‘H‘ should be used for 24-hour Hour format
- Small-letter ‘h‘ should be used for 12-hour Hour format
- Small-letter ‘m‘ should be used for Minute
- Small-letter ‘s‘ should be used for Second
- Small-letter ‘n‘ should be used for Nanosecond

+ offsetDateTime);
// 2. DateTimeFormatter
DateTimeFormatter dateTimeFormatter = DateTimeFormatter
.ofPattern("dd.mmm.yyyy HH:mm:ss.nnn XXX");
// 3. OffsetDateTime to (dd.mmm.yyyy HH:mm:ss.nnn XXX) format in String form
