我的代码根本无法运行。以前，它找不到.fxml文件。清洗溶液后，我得到了这个错误。我相信主要的问题就在这里。我已将完整错误上传到pastebin中。我的FXML和其他.java文件一样都在src下

https://pastebin.com/guKHAG3p

try {
    String input = "2019-09-23";

    // convert String to Date
    DateFormat format = new SimpleDateFormat("yyyy-MM-dd");
    Date date = format.parse(input);

    // convert Date to String
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
    String dateString = simpleDateFormat.format(date);

    System.out.println(dateString);
} catch (ParseException e) {
    e.printStackTrace();
}

产生于：javafx.fxml.LoadException： /C:/Users/jinyi/Desktop/CIS%2022C/CoronavirusUpdate/bin/fxml.fxml
