反序列化对象java列表 - ＆gt; INVALID STREAM HEADER

Question

我有一个简单的类Ksiazka并尝试序列化和反序列化它的列表。首先，我需要从文件“bibdefaout.txt”加载它。我一直收到错误：

Exception in thread "main" java.io.StreamCorruptedException: invalid stream header: 5AB36F64
    at java.io.ObjectInputStream.readStreamHeader(Unknown Source)
    at java.io.ObjectInputStream.<init>(Unknown Source)
    at zadanie.Zadanie.main(Zadanie.java:17)

请告诉我我做错了什么：

public class Ksiazka implements Serializable{
    protected String tytul;
    protected String autor;
    protected Integer rok;
    protected boolean wypozyczenie;

    public Ksiazka(String tytul, String autor, Integer rok, boolean wypozyczenie) {
        this.tytul = tytul;
        this.autor = autor;
        this.rok = rok;
        this.wypozyczenie = wypozyczenie;
    }
}

public class Zadanie {
    public static void main(String[] args)
            throws FileNotFoundException,IOException, ClassNotFoundException {
        List<Ksiazka> lista;
        // THE FOLLOWING LINE PRODUCES AN ERROR:
        FileInputStream fin=new FileInputStream("bibdefault.txt");
        ObjectInputStream oin=new ObjectInputStream(fin);
        lista=(List<Ksiazka>)oin.readObject();
        fin.close();
        oin.close();

        try {
            ObjectOutputStream out=new ObjectOutputStream(new BufferedOutputStream(new FileOutputStream("bibloteka.out")));
            out.writeObject(daneLista);
            out.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

文件写错了，并没有包含正确的序列化数据。它也没有发生在您声称的行上，因为它无法抛出该异常。
