我正在尝试序列化 JSONObjects 的 ArrayList。但是我得到错误:

这是我的序列化和反序列化代码:
private void serializeQuotes() {
FileOutputStream fos;
try {
fos = openFileOutput(Constants.FILENAME, Context.MODE_PRIVATE);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(quotes);
oos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
@SuppressWarnings("unchecked")
private void deserializeQuotes() {
try {
FileInputStream fis = openFileInput(Constants.FILENAME);
ObjectInputStream ois = new ObjectInputStream(fis);
quotes = (ArrayList<JSONObject>) ois.readObject();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
