Q:

Obtaining date from JDateChooser and displaying it in JTextField

I have constructed the following JDateChooser:
availFromDate = new JDateChooser();
availFromDate.setDateFormatString("dd/MM/yyyy");
JTextFieldDateEditor dateEditor = (JTextFieldDateEditor)availFromDate.getComponent(1);
dateEditor.setHorizontalAlignment(JTextField.RIGHT);
availFromDate.setSize(new Dimension(50, 0));
availFromDate.add(availablefromT);
calendarP.add(availFromDate);
contentPane.add(calendarP);
frame1.add(contentPane);
frame1.setVisible(true);

However, I need the date selected from the JDateChooser to appear in the JTextField it is being held in. I realise there must be a getDate() method involved, though I am not sure how to implement it. 
How do I obtain the date and display it within the textfield in the format of dd/MM/yyyy?
Edit: 
I have tried the following after seeing suggestions: 
  SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
  String date = sdf.format(availFromDate.getDate());
  availablefromT.setText(date);

Though, now I am getting a NullPointerException. Anyone know why? It seems to concern this: String date = sdf.format(availFromDate.getDate());
The Error(s):

        //////////// Creating Frame
        chooseCruiseFrame = new JFrame("");
        chooseCruiseFrame.setSize(300, 200);
        chooseCruiseFrame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
        chooseCruiseFrame.setVisible(true);

        // Available From Calendar
        JLabel availF = new JLabel("Available From:");
        centerP.add(availF);
        contentPane.add(centerP);
        availablefromT = new JTextField(11);
        centerP.add(availablefromT);

        chooseCruiseFrame.setVisible(true);

        // Converting Date to String
        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
        String date = sdf.format(availFromDate.getDate());
        availablefromT.setText(date);
    }
}

A:

the same code works here
   //button    

        private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {                                         

        DateFormat fmt = new SimpleDateFormat("dd/MM/yyyy");
        String date = fmt.format(this.txt_data_ini.getDate()); //jdatechooser
        this.teste.setText(date);

    }
