I have a JTable.I have JSpinner class in One of its column.When user click it a instance of JSpiner opens with JSpinnerDateModel.It has two features.One can use Spinner up/down button to change time.And one can write time by typing.I am using am/pm 12-hour format.Now i want that when user type,he is not able to delete colon using backspace.WHile using backspace when colon arrives,cursor moves one step ahead.

public class TimeEditor extends DefaultCellEditor{

   private JSpinner timeSpinner;
   SpinnerDateModel model;
   JSpinner.DateEditor de;




   TimeEditor(JFormattedTextField jf){ 

      super(jf);
      model = new SpinnerDateModel();
      model.setCalendarField(Calendar.MINUTE);

      timeSpinner = new JSpinner();

      timeSpinner.setModel(model);
      de= new JSpinner.DateEditor(timeSpinner, "hh:mm a");

      timeSpinner.setEditor(new JSpinner.DateEditor(timeSpinner, "h:mm a"));
      timeSpinner.setBorder(null);


}

And the code from where i am calling time editor is

` String mask = "**:*****"; MaskFormatter timeFormatter; JFormattedTextField formattedField; public TestCalculator(){ initComponents(); getContentPane().setBackground(Color.LIGHT_GRAY);

     try{
        timeFormatter = new MaskFormatter(mask);
        timeFormatter.setPlaceholderCharacter(':');
        formattedField = new JFormattedTextField(timeFormatter);
      }
      catch(ParseException e){
          e.printStackTrace();
      }

  • @AnuradhaSharma What *exactly* isn't working? "*It is not working*" isn't a very satisfying description... Did you make sure to catch / throw the `ParseException`? If that doesn't help, please consider to edit your answer by posting a [mcve] that is producing the problem. – Lukas Rotter Feb 13 '16 at 21:42
