没有太多 Java 经验，但我目前正在编写一个非常基本的 JavaFX 应用程序，并尝试从 Excel 文件中读取信息。这一切都工作正常，但是，我遇到的问题是当尝试通过打开警报对话框而不是将它们打印到终端窗口来处理错误时。我目前已经得到了下面的代码，但无论出于何种原因，用户界面上没有任何反应，而是打印了下面的错误。任何帮助将不胜感激。#
protected void uploadNames() {
try {
FileChooser fileChooser = new FileChooser();
File selectedFile = fileChooser.showOpenDialog(stage);
FileInputStream file = new FileInputStream(selectedFile);
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet spreadsheet = workbook.getSheetAt(0);
for (int i = 0; i < spreadsheet.getLastRowNum(); i++) {
TextField textField = new TextField(spreadsheet.getRow(i).getCell(0).toString());
textField.setEditable(false);
namesList.getChildren().add(textField);
arrayNamesList.add(textField);
textField.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
namesList.getChildren().remove(textField);
arrayNamesList.remove(textField);
}
});
}
} catch (IOException e) {
Alert.AlertType alertType = Alert.AlertType.ERROR;
Alert alert = new Alert(alertType, "Error");
alert.getDialogPane().setContentText("Just checking this box open when error is found");
alert.showAndWait();
}
}

我也尝试过使用抛出异常的方法，并尝试在调用该方法时执行 try 和 catch，但这产生了相同的结果。

请注意，这将阻止异常传播。由于您的
