         int row = bookingTable.getSelectedRow();
         if(row<0){

         }
         else{
            final String roomType = ((BookingTableModel)bookingTable.getModel()).getValueAt(row,3).toString();
            =============================================================
            final double totalPrice = (Double.parseDouble((BookingTableModel)bookingTable.getModel()).getValueAt(row,9).toString());
             =============================================================
            final String memberName = ((BookingTableModel)bookingTable.getModel()).getValueAt(row,7).toString();
            final String receptionistName = ((BookingTableModel)bookingTable.getModel()).getValueAt(row,8).toString();
            final String appStatus = ((BookingTableModel)bookingTable.getModel()).getValueAt(row,5).toString();
            final String appID = ((BookingTableModel)bookingTable.getModel()).getValueAt(row,0).toString();
            if(appStatus.equals("CheckOut") || appStatus.equals("Cancel")){
                JOptionPane.showMessageDialog(null, "The booking either CheckOut or canceled","ERROR",JOptionPane.ERROR_MESSAGE);
            }
            else {
               SwingUtilities.invokeLater(new Runnable(){
                   @Override
                   public void run() {
                       CheckInRecordServiceJFrame checkInRecordServiceJFrame = new CheckInRecordServiceJFrame(getPanel(),roomType,memberName,receptionistName,totalPrice,appID);
                   }
               });
            }
         }
}

我有一个问题是我无法将 table 模型转换为字符串。在上面的代码中，我想将双精度转换为字符串，但是 errors.Please 帮我解决了这个问题。
