DateFormatter is not printing value in the given format

Question

My date-time format string is : yyyy-MM-dd'T'HH:mm:ss.SSSZ
I am using DateTimeFormatter from Joda Time to print my date in the above mentioned format.

Now, consider the date as

2016/04/01 23:00:00

then it should have printed

2016-04-01T23:00:00.000Z

But, it prints

2016-04-01T23:00:00.000+0200

Please help me in getting the date printed in the same format as specified in the string format.

Answer 1

According https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html Z has special meaning:

Z       zone-offset

If you want to escape Z quote Z with ':

yyyy-MM-dd'T'HH:mm:ss.SSS'Z'

For example:

java.time.LocalDateTime date = java.time.LocalDateTime.now();
java.time.format.DateTimeFormatter formatter = java.time.format.DateTimeFormatter
                .ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
java.lang.String text = date.format(formatter);
System.out.println(text);

prints

2016-06-11T18:39:41.962Z
