          cost=rs.getString("cost");
      }

      if("".equals(currDate)){   //CHECK IF THE DATE IN DATABASE IS EMPTY
          serviceDate=null;  //IF TRUE THEN ASSIGN TO CURRENT DATE EMPTY VALUE
      }else if(NextServiceDate.getDate()!=null){   //ELSE
          //String date=((JTextField)NextServiceDate.getDateEditor().getUiComponent()).getText();   //GET THE VALUE FROM JDATECHOOSER FORMAT DATE TO STRING

      }else if(txtcost.getText()!=null){ //ELSE IF COST TEXTFIELD IN NOT NULL

在应用程序中我保存客户个人信息和下一个服务的日期和成本。所以我将jdatechooser日期转换为(yyyy-mm-dd),以便我可以与当前系统日期进行比较并显示一条消息必须告知客户他们的汽车服务。 这是一个小应用程序,只是为了存储我的客户,我努力解决出现的问题。 提前谢谢。
