How to format Joda-Time DateTime to only mm/dd/yyyy?

Question

I have a string \"11/15/2013 08:00:00\", I want to format it to \"11/15/2013\", what is the correct DateTimeFormatter pattern?

Answer 1

I am adding this here even though the other answers are completely acceptable. JodaTime has parsers pre built in DateTimeFormat:

dateTime.toString(DateTimeFormat.longDate());

This is most of the options printed out with their format:

shortDate:         11/3/16
shortDateTime:     11/3/16 4:25 AM
mediumDate:        Nov 3, 2016
mediumDateTime:    Nov 3, 2016 4:25:35 AM
longDate:          November 3, 2016
longDateTime:      November 3, 2016 4:25:35 AM MDT
fullDate:          Thursday, November 3, 2016
fullDateTime:      Thursday, November 3, 2016 4:25:35 AM Mountain Daylight Time

Answer 2

UPDATED:

You can: create a constant:

private static final DateTimeFormatter DATE_FORMATTER_YYYY_MM_DD =
          DateTimeFormat.forPattern("yyyy-MM-dd"); // or whatever pattern that you need.

This DateTimeFormat is importing from: (be careful with that)

import org.joda.time.format.DateTimeFormat; import org.joda.time.format.DateTimeFormatter;

Parse the Date with:

DateTime.parse(dateTimeScheduled.toString(), DATE_FORMATTER_YYYY_MM_DD);

Before:
DateTime.parse("201711201515",DateTimeFormat.forPattern("yyyyMMddHHmm")).toString("yyyyMMdd");

if want datetime:

DateTime.parse("201711201515", DateTimeFormat.forPattern("yyyyMMddHHmm")).withTimeAtStartOfDay();

Answer 3

I think this will work, if you are using JodaTime:

String strDateTime = "11/15/2013 08:00:00";
DateTime dateTime = DateTime.parse(strDateTime);
DateTimeFormatter fmt = DateTimeFormat.forPattern("MM/dd/YYYY");
String strDateOnly = fmt.print(dateTime);

I got part of this from here.

Answer 4

Please try to this one

public void Method(Datetime time)
{
    time.toString("yyyy-MM-dd'T'HH:mm:ss"));
}

Answer 5

DateTime date = DateTime.now().withTimeAtStartOfDay();
date.toString("HH:mm:ss")

Answer 6

Another way of doing that is:

String date = dateAndTime.substring(0, dateAndTime.indexOf(" "));

I'm not exactly certain, but I think this might be faster/use less memory than using the .split() method.
