Issue with parsing Date string

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?

java.time

In 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).

Solution using modern date-time API

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

Online Demo

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);

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.

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();
}
