I'm trying to parse the following string to a Date object:
2013-12-26T01:00:56.664Z
Using this SimpleDateFormat:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
But I'm getting a:
java.text.ParseException: Unparseable date: "2013-12-26T01:00:56.664Z" (at offset 19)
What am I doing wrong, How I should handle the T and the Z letters in the date?
The real isssue with the date is not T & Z but the milliseconds.
"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" This must be the format that is to be used becaue there are milli seconds as well in the input date.
Z in the string to be parsed is a UTC offset of 0 and needs to be parsed as an offset. When instead you quote it as a literal in the format pattern string, you are getting the wrong result )in the vast majority of time zones).java.timeIn March 2014, Java 8 introduced the modern, java.time date-time API which supplanted the error-prone legacy java.util date-time API. Any new code should use the java.time API.
On a side note, never specify 'Z' in a date-time parsing/formatting pattern because 'Z' is a character literal while Z is a pattern character specifying time zone offset. To parse a string representing a time zone offset, you must use X (or XX or XXX depending on the requirement).
Since your date-time string is in the default format used by Instant#parse, you can parse it to an Instant directly.
Demo:
import java.time.Instant;
public class Main {
public static void main(String[] args) {
Instant instant = Instant.parse("2013-12-26T01:00:56.664Z");
System.out.println(instant);
}
}
Output:
2013-12-26T01:00:56.664Z
Note: For whatever reason, if you need an instance of java.util.Date from this object of Instant, you can do so as follows:
java.util.Date date = Date.from(instant);
Learn more about the modern date-time API from Trail: Date Time.
You can use this
String date = "2013-12-26T01:00:56.664Z";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
try {
System.out.println(sdf.parse(date)); // Result Thu Dec 26 01:00:56 CET 2013
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormatin its day was a notorious troublemaker of a class, so since it has been outdated for 10 years, you should never use it any more.Tcorrectly by enclosing it in single quotes, as a literal; but you must never do that withZ.Zis a UTC offset (of zero) and must be parsed as an offset, or you get an incorrect result.
