4. 异常对话框

这不是一个完整的异常对话框。但我们可以很容易地将 TextArea 作为可扩展的内容。

Alert alert = new Alert(AlertType.ERROR);
alert.setTitle("Exception Dialog");
alert.setHeaderText("Look, an Exception Dialog");
alert.setContentText("Could not find file blabla.txt!");

Exception ex = new FileNotFoundException("Could not find file blabla.txt");
