сохранить фолио как объекты в файле Java

0 голосов
/ 23 ноября 2018

Я пытаюсь создать программу, в которой пользователь сможет создавать фолио, покупать / продавать акции и т. Д. Я хочу создать кнопку сохранения, чтобы пользователь мог сохранить свой текущий фолио.IPortofolioDb - это интерфейс PortofolioDb, в котором реализованы все методы для пользовательских данных.Я пытался сделать следующее, но это не работает, и у меня буквально кончились иды.Может кто-нибудь мне помочь ?

public class saveFolioListener implements ActionListener {
    private Gui g;
    private IPortfolioDb folios;

    public saveFolioListener(Gui g, IPortfolioDb folios) {
        this.g = g;
        this.folios = folios;
    }

    @Override
    public void actionPerformed(ActionEvent arg0) {

        String fileName= "data.txt";
        try {
            ObjectOutputStream os = new ObjectOutputStream(new FileOutputStream(fileName));
            os.writeObject(folios);
            os.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("saved");

    }

}
