How to get a Date from a JSON object

Question

I have a JSON object, which have one field that is a birthdate:

JSONObject obj = new JSONObject(response);
User user = new User();
user.setuserID(obj.getString("userID"));
user.setisMale(obj.getBoolean("isMale"));
user.setEmail(obj.getString("email"));
// user.setBirthdate(obj.getDate("birthdate"));
user.setLastName(obj.getString("lastName"));
user.setFirstName(obj.getString("firstName"));

But the method getDate() does not exist in JSONObject.
How can I set the Birthdate in my User object?

How is your date represented in the JSON response? I guess a String? Show the JSON. — Lukas Knuth, Apr 02 '13 at 09:55

You may do like below,

String dateStr = obj.getString("birthdate");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date birthDate = sdf.parse(dateStr);
//then
user.setBirthdate(birthDate);

Hope to help you :)

It resulted, but it is printing `Wed Aug 01 00:00:00 BST 2012`, even my format is `SimpleDateFormat("yyyy-MM-dd")` – user2144555 Apr 02 '13 at 10:11
your result is normal, because the format partten is "yyyy-MM-dd", please use "yyyy-MM-dd HH:mm:ss" to get hours, minutes and seconds. – Hunter Zhao Apr 02 '13 at 10:14

I would prefer the onliner new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").parse(dateStr) – Pablo Pazos Aug 29 '18 at 05:20

In general, a date is passed as milliseconds or as a formatted string. So depending upon your json you can use either use new Date(json.getLong(milliseconds)) or if date is in string

String birthdate = json.getString(date);//"2013-03-26"
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
