Can't get date from DateChooserCombo

Question

I'm trying to get the date from DateChooserCombo as follows

SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-DD");
String date = sdf.format(dateChooser.getDate());

But the method getDate() gives me error (illegal forward reference). I have also tried with getSelectedDate() but it's the same. What can I do?

Anyway I'm using Apache Netbeans 12.1 and the date picker should be this one: https://github.com/vadimig/jdatechooser

Thanks.

I downloaded the JDateChooser code from the link you provided in your question. There is no getDate() method in class datechooser.beans.DateChooserCombo. There is a getSelectedDate() method which returns an instance of class java.util.Calendar.

Also, according to the documentation for class java.text.SimpleDateFormat, the pattern YYYY-MM-DD is a valid pattern but I don't think it's the pattern that you want. D means day in year which means that 27^th February is the 58^th day of the year. You probably want d. Similarly, Y means Week year whereas you probably wanted y.

So, in order to get a string representation of the date that the user selected from the DateChooserCombo, you probably want the following code.

DateChooserCombo dcc = new DateChooserCombo(); // or however you create and configure it
Calendar cal = dcc.getSelectedDate();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String date = sdf.format(cal.getTime());

By the way, it appears that JDateChooser development stopped seven years ago. Perhaps consider using JavaFX which has a DatePicker component which works with Java's date-time API.
