Trying to use Calendar instance for p:datePicker component

Question

I am working on a PrimeFaces project and since the 10.0 migration the p:calendar component in my xhtml is deprecated. I have replaced it with p:datePicker, but I don't know if I can still use these line of codes to get the DatePicker instance in the bean:

Calendar calendar = Calendar.getInstance();
calendar.setTime(startDate);

Also, do I have to convert my Dates to LocalDate?

I have tried to keep these lines of codes that were working with the p:calendar component, but it doesn't fire the methods associated in the p:ajax tag.

Although, technically, if you write a converter, it will be possible to use Calendar with p:datePicker. However, I would bite the bullet and migrate to the Java 8 date time API instead of converting your Calendars to Date. If you are already using Dates, you can use them with the p:datePicker (although I would still consider converting them to a more modern type).

So from what I understand I could use LocalDateTime instead of Date and I wouldn't need a converter in the xhtml. Thank you for your answer ! – rookie Mar 03 '23 at 14:04
Both `Date` and `LocalDateTime` will work OOTB. `Calendar` won't. – Jasper de Vries Mar 03 '23 at 14:07
So using an instance of calendar wouldn't be the best solution, I understand, thank you – rookie Mar 03 '23 at 14:29
