title: Obtaining date from JDateChooser and displaying it in JTextField
body: <p>I have constructed the following JDateChooser:</p>
  
  <pre><code>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);
  </code></pre>
  
  <p>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. </p>
  
  <p>How do I obtain the date and display it within the textfield in the format of dd/MM/yyyy?</p>
  
  <p><strong>Edit:</strong> </p>
  
  <p>I have tried the following after seeing suggestions: </p>
  
  <pre><code>  SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
    String date = sdf.format(availFromDate.getDate());
    availablefromT.setText(date);
  </code></pre>
  
  <p>Though, now I am getting a NullPointerException. Anyone know why? It seems to concern this: <code>String date = sdf.format(availFromDate.getDate());</code></p>
  
  <p>The Error(s):</p>
