I want to convert date from String to LocalDate object: Starting date as String: "12/11/2022" I want to convert this String to LocalDate. I want to get LocalDate object and next use this LocalData inside if-else conditions to convert this object to String and return String. All conditions return first LocalData and next String as result: if I use this code with: date = LocalDate.parse(default)};
public String getStringDate(String timeProjection){
if (timeProjection.equals("1") {
date = LocalDate.now();
}
....
else {
String default = "12/11/2022";
date = LocalDate.parse(default);
}
command
return date.format(DataTimeFormatter.ofPattern("dd/MM/YYYY"));
I get issue that is impossible this parse, but when I use:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/YYYY");
String date = "16/08/2016";
LocalDate localDate = LocalDate.parse(date, formatter);
This convertion works good. What do you think is possible create solution when I can't use twice this formatter: DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/YYYY") - first in else body, second in result command? Thanks for your help.

I get a datetime string from an C# API that looks like this "2021-05-07T08:58:15.993". I am trying to convert it to "2021-05-07 08:58 AM" for my android app. I am using this code:
fun convertStringToDate(stringDate: String): LocalDate? {
val formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm ", Locale.ENGLISH)
val date = LocalDate.parse(stringDate, formatter)
return date
}
but it gives me an error of DateTimeParseException "2021-05-07T08:58:15.993" could not be parsed at index 10.
Index 10 is the 'T' character. I could just hack it and just remove the T and remove the .993, but, what if the date format changes from the API?

Hello I am trying to convert sql date format to "dd-MM-yyyy" but in the output I have this unwanted format which shows the current date time (Mon Aug 14 00.00....)
String inputDate = rs.getDate("BIRTH_DATE").toString();
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
Date outputDate = formatter.parse(inputDate);
user.setBirthdate(outputDate);

Dates do not have an inherent format.
java.util.Date inputDate = rs.getDate("BIRTH_DATE");
user.setBirthdate(inputDate);
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
String representation = formatter.format(inputDate);
It would be better to use the new java.time classes: LocalDate, ZonedDateTime and so on.

You can use DateTimeFormatter with withLocale.
Parsing text.
DateTimeFormatter dateTimeFormatter =
DateTimeFormatter
.ofPattern("dd MMMM uuuu")
.withLocale( new Locale("ru") )
;
LocalDate ld = LocalDate.parse(rDate, dateTimeFormatter);
Generating text.
String usDate = ld.format(DateTimeFormatter.ofPattern("dd-MM-uuuu"));
=> 28-08-2017

I receive this "10/1/2018, 1:27:42 PM" as date from server. Now want to convert it to SimpleDateFormat("yyyy-MM-dd HH:mm:ss"). But to do this i need to know the format of existing date string.
How i can find a correct format of "10/1/2018, 1:27:42 PM"?

You need to use SimpleDateFormat.toPattern() to get the pattern. Use this function in this way -
SimpleDateFormat sdf = new SimpleDateFormat();
// get the current date and time
Calendar cal = Calendar.getInstance();
String dateToday = sdf.format(cal.getTime());
// get the pattern used by the formatter and print it
String pattern = sdf.toPattern();
System.out.println("Pattern:"+pattern);
