我有一个新的JavaFx Project，我需要将Obj保存为文件 但是我有一些例外该如何解决？ 我知道例外只在第41行（oos.writeObject（Ob）;）
例外：
第21行是我触发SavePage函数的地方 第41行是我写“ oos.writeObject（Ob）”的地方
private void SavePage() throws FileNotFoundException,IOException {
Stage stage = new Stage();
stage.setTitle("Save FILE");
FileChooser getFile = new FileChooser();
getFile.getExtensionFilters().add(new FileChooser.ExtensionFilter("Sina FILE", "*.sina"));
getFile.getExtensionFilters().add(new FileChooser.ExtensionFilter("Thina FILE", "*.thn"));
File file = getFile.showSaveDialog(stage);
String path= file.toString();
String name = file.getName();
String text = TextArea.getText();
FILE Ob = new FILE(text,name,path,FNAME,FSIZE);
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(new File(".\\110.txt")));
oos.writeObject(Ob);
}
