SWING JTable, cell start to edit event

I have a JTable and these cells of it are editable, there are any ways to handle the "cell start to edit" event in order that I can display a message when users start to edit a cell.

Add a PropertyChangeListener to the JTable:

//
//  Implement the PropertyChangeListener interface
//
    @Override
    public void propertyChange(PropertyChangeEvent e)
    {
        //  A cell has started/stopped editing

        if ("tableCellEditor".equals(e.getPropertyName()))
        {
            if (table.isEditing())
                // code for editing started;
            else
                // code for editing stopped;
        }
    }

If this were my code, I'd start by trying to override the TableEditor's getTableCellEditorComponent method. Inside of the override, I'd call the method that I want to call when editing starts, and then I'd call the super's getTableCellEditorComponent method inside the override.

You can find out more details on how to use custom cell editors (since this is what you need to do) at the JTable tutorial.
