Get value from Date picker


I want to get the value from JavaFX datepicker and store the value as Date Object:

final DatePicker datePicker = new DatePicker(;
Date date = datePicker.getValue();
grid.add(datePicker, 1, 9);

Can you tell me how I can convert LocalDate to Date?

Accepted Answer

As the name implies, LocalDate does not store a timezone nor the time of day. Therefore to convert to an absolute time you must specify the timezone and time of day. There is a simple method to do both, atStartOfDay(ZoneId). Here I use the default time zone which is the local timezone of the computer. This gives you an Instant object which represents and instant in time. Finally, Java 8 added a factory method to Date to construct from an Instant.

LocalDate localDate = datePicker.getValue();
Instant instant = Instant.from(localDate.atStartOfDay(ZoneId.systemDefault()));
Date date = Date.from(instant);
System.out.println(localDate + "\n" + instant + "\n" + date);

This will give you an output like below. Note that the Instant by default prints in UTC.

Of course, you will need to convert your java.util.Date into a java.time.LocalDate to set the value on the DatePicker. For that you will need something like this:

Date date = new Date();
Instant instant = date.toInstant();
LocalDate localDate = instant.atZone(ZoneId.systemDefault()).toLocalDate();
System.out.println(date + "\n" + instant + "\n" + localDate);

Which will give you output like:

Tue Feb 25 08:47:04 CST 2014
2/25/2014 2:49:22 PM

Or you can use more simplest way

java.sql.Date gettedDatePickerDate = java.sql.Date.valueOf(myDatePicker.getValue());

And then you can perform operation within this date object.

Convert to java.util.Date
