Can not retrieve date from JDateChooser in Java

问题

I am using JDateChooser from here

However I can not retrieve the date in format set with the method setDateFormatString while displaying it in console.

In first label shows actual date retrieved from JDateChooser while second label shows the format which I have set. When I select date from JDateChooser I get the date as 22-07-2011 as shown in image. But when I use getDate method, it will give me date as Fri Jul 22 00:00:00 GMT+05:30 2011. I want only 22-07-2011.

Here is my code. I am using Netbeans IDE 7.0

public JDateChooser() {
    initComponents();
    dateChooser.setDateFormatString("dd-MM-yyyy");
}
private void btnDisplayDateActionPerformed(java.awt.event.ActionEvent evt) {
    String dateFromDateChooser = dateChooser.getDate().toString();
    lblDate.setText(dateFromDateChooser);
    lblDateFormat.setText(dateChooser.getDateFormatString().toString());
    System.out.println(dateFromDateChooser);
}
public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {

        @Override
        public void run() {
            new JDateChooser().setVisible(true);
        }
    });
}

回答1:

You can use the String.format method to get the desired result.

Date dateFromDateChooser = dateChooser.getDate();
String dateString = String.format("%1$td-%1$tm-%1$tY", dateFromDateChooser);

回答2:

Try this

java.text.SimpleDateFormat fmt = new java.text.SimpleDateFormat("dd-MM-yyyy");
String formattedDate = fmt.format(dateChooser.getDate());

回答3:

there are two choises

1/ you already dowloaded code source

    calDealDate.setPreferredSize(new Dimension(90, 23));
    calDealDate.setDateFormat(new SimpleDateFormat("dd.MM.yyyy"));
    calDealDate.setSpiningCalendarField(Calendar.DAY_OF_MONTH);
    calDealDate.setFont(new Font("SansSerif", Font.BOLD, 12));
    calDealDate.setBackground(AppVariables.fieldColor);
    calDealDate.addChangeListener(new ChangeListener() {

        @Override
        public void stateChanged(ChangeEvent e) {
            //here is your date depends of previous setings
        }
    });
    calDealDate.setToolTipText(" some tooltip text  ");

2/ you already dowloaded jar file, then you have to find this method or equivalent from API

EDIT: maybe I would be preffered to start with code source, just import that into project

Try This one

   public void calendarExpale(){
    JPanel content = new JPanel();
    content.setLayout(new FlowLayout());
    final JTextField textField = new JTextField(15);
    JDateChooser chooser = new JDateChooser();

   chooser.setSize(15, 10);
  chooser.addPropertyChangeListener("date", new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent evt) {

    JDateChooser chooser = (JDateChooser)evt.getSource();
    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:MM:SS");
    textField.setText(formatter.format(chooser.getDate()));
}
  });

  content.add(textField);
    content.add(chooser);
}
