I am using java. I have used JDateChooser to select a date. now I want to display the day (line Sunday, Monday or else day of week) of the selected date. I know how to add JDateChooser but don't know how to get the day of week of selected date. Please help.

JDateChooser will return an instance of java.util.Date, which is, frankly, less than useless now days.

The trick here is to covert the Date value to a LocalDateTime value, for example...

Date date = new Date();
LocalDateTime ldt = date.toInstant()
        .atZone(ZoneId.systemDefault())
        .toLocalDateTime();

Then you can simply query the dayOfWeek value... 

DayOfWeek dow = ldt.getDayOfWeek();
System.out.println(dow.name());

Now you can use the DayOfWeek#name value or, because it's a enum, generate your own output as you need

    Instead of ' Date date = new Date(); ' I have used ' java.util.Date date= jDateChooser1.getDate(); ' . Note I have Used java swing drag and drop . rest the code worked fine for me. – Meera Bisht Aug 01 '19 at 05:11
  • It's the good answer. A detail, if the date chooser doesn't give any meaningful time of day, I'd use `toLocalDate` to obtain a `LocalDate` rather than a `LocalDateTime`. – Ole V.V. Aug 01 '19 at 05:23
  • @meeraBisht Yeah, it was all just using it as demonstration ;) – MadProgrammer Aug 01 '19 at 05:32
