I have the birthday date 04 December I want to save it as 04-12 in the database, for that I do this:
val birthday = theForm.field("birthday") //String
val date = new java.text.SimpleDateFormat("dd-mm", Locale.ENGLISH).parse(birthday)
But i get the error: ParseException: Unparseable date: "04 December"
Any idea? Thanks!
Your date format string is not correct. Try it as "dd MMMM". The javadocs for SimpleDateFormat are pretty comprehensive for format possibilities:
http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
It seems like you want to parse it as one format and then re-format it into another. For this you can use two separate SimpleDateFormat instances, one with "dd MMMM" for parsing the 04 December format and one with "dd-MM" for re-formatting into the format you want to save to your db. The code would look like this:
val date = new SimpleDateFormat("dd MMMM", Locale.ENGLISH).parse(birthday)
val dbDateString = new SimpleDateFormat("dd-MM", Locale.ENGLISH).format(date)
What about:
import java.time._
val birthDay = MonthDay.parse("--12-04")

Tried searching around couldn't really find anything. Was hoping to find a way to revert the datetime format.
So I start off with: 4-11-22 and I want to change to Friday, 12 November 2022.
Using the intl package
import intl package
import 'package:intl/intl.dart';
Then, you can do as follows:
String myDate = '4-11-22'; // input date
String pattern = 'dd-MM-yy'; // define parse pattern for the input date
DateTime date = DateFormat(pattern).parse(myDate); // parse the input date
String newPattern = 'EEEE, dd MMMM yyyy'; // define new pattern
String formattedDate = DateFormat(newPattern).format(date); // reformat
print(formattedDate); // result: Friday, 04 November 2022
Try on DartPad
For more formatting possibilities, go to the docs.
final oldDateDateTime = DateFormat('dd-MM-yy').parse('4-11-22');
final newDateString = DateFormat('EEEE, d MMMM y', 'en_US').format(oldDateDateTime);
print(oldDateDateTime.toString());
print(newDateString);
Output:
2022-11-04 00:00:00.000
Friday, 4 November 2022
More in: https://pub.dev/documentation/intl/latest/intl/DateFormat-class.html
You can do as follows
final DateFormat formatter = DateFormat('EEEE, dd MMMM yyyy');
final String formatted = formatter.format(DateTime.now());
Then you use the formatted
I am using Scala spark.I have two similar CSV files with 10 columns.One difference is with the Date column format.
1st file Date format yyyy-MM-dd
2nd file Date format dd-MM-yyyy
Objective is to: create seperate schema rdd for each file and finally merge both the Rdds.
For the first case class, I have used Date.valueOf [java.sql.Date] in the case class mapping.No issues here..
Am finding issue with the 2nd file Date format..
I have used the same Date.valueOf mapping..but it's throwing error in the date format...
How can I map the date format in the second file as like the 1st format yyyy-MM-dd? Please assist
Use java.util.Date:
val sDate1="31/12/1998"
val date1=new SimpleDateFormat("dd/MM/yyyy").parse(sDate1)
import java.text.SimpleDateFormat
Result:
sDate1: String = 31/12/1998
date1: java.util.Date = Thu Dec 31 00:00:00 CET 1998
to change the output format as a common string format.
val date2=new SimpleDateFormat("yyyy/MM/dd")
date2.format(date1)
Result:
res1: String = 1998/12/31
I'm trying to save a date to MongoDB from FullCalendar in my Grails application.
I'm trying to parse the string 2015-12-27T00:00:00.000Z into the below format:
def startDate = new Date().parse("YYYY-MM-dd'T'HH:mm:ss.SSSXXX",it.start)
def endDate = new Date().parse("YYYY-MM-dd'T'HH:mm:ss.SSSXXX",it.end)
But, weirdly when I print the formatted date, I get Sun Dec 28 05:30:00 IST 2014. I don't know what or how that particular date is picked.
You should use lowercase y for year. Uppercase Y is for "Week year".
new Date().parse("yyyy-MM-dd'T'HH:mm:ss.SSSXXX", "2015-12-27T00:00:00.000Z")
===> Sat Dec 26 19:00:00 EST 2015
import java.text.SimpleDateFormat;
println new SimpleDateFormat("yyyy-MM-dd HH:mm:ssX").parse("2018-07-30 09:57:15 +0800")
I'd like to get the day from a date object as an integer. This is my code so far.
val dateString = "2015-11-24 23:23:09"
val format = new java.text.SimpleDateFormat("yyyy-MM-dd H:m:s")
val date = format.parse(dateString)
print(date) # this gives Tue Nov 24 23:23:09 CST 2015
Now, from date, I want to get the day of the month as an integer. How do I do that?
Thanks.
Just use the Java Calendar class (although I would recommend moving over to the Joda library if you are doing much serious work with dates/times):
val cal = Calendar.getInstance()
cal.setTime(date)
val dayOfMonth = cal.get(Calendar.DAY_OF_MONTH)
tl;dr
LocalDateTime.parse(
"2015-11-24 23:23:09".replace( " " , "T" )
).getDayOfMonth()
java.time
The modern approach uses the java.time classes.
Using Java syntax here as I don't know Scala. Note that java.time uses immutable objects.
Convert your string to comply with ISO 8601 standard format with a T in the middle.
String input = "2015-11-24 23:23:09".replace( " " , "T" ) ;
Parse as an LocalDateTime as your input lacks any time zone or offset-from-UTC.
LocalDateTime ldt = LocalDateTime.parse( input ) ;
Interrogate for the day of month.
int dom = ldt.getDayOfMonth() ;
Using Joda,
org.joda.time.DateTime.now().getDayOfMonth()
or equivalently,
import java.util.Date
new org.joda.time.DateTime(new Date()).getDayOfMonth
Convert Long date format to specific short date format.
I want to get the Date from Datepicker(Jcalander) , format to dd-mm-yyyy format and assign to String variable. I tried using codes shown below. But didnt get the date format i want.
SimpleDateFormat simpleFormat = (SimpleDateFormat) jCalendarCombo1.getDateFormat();
Date date = jCalendarCombo1.getDate();
System.out.println(date); // Prints Thu Mar 28 00:00:00 IST 2013
String s = simpleFormat.format(date);
System.out.println(s); // prints Thursday, March 28, 2013
System.out.println("Date SHORT format: " + DateFormat.getDateInstance(DateFormat.SHORT).format(date)); // prints 3/28/13
If you want a fixed, non locale dependent format, you can just create it yourself;
SimpleDateFormat shortformat = new SimpleDateFormat("dd-MM-yyyy");
String s = shortformat.format(date);
System.out.println(s); // Prints 29-03-2013
