1.如下程式碼，將檔案2.log序列化後儲存到2.txt

    FileInputStream fin = new FileInputStream("D:\2.log");

    FileOutputStream out1 = new FileOutputStream(new File("D:\2.txt"));

    // ObjectOutputStream oop1 = new ObjectOutputStream(out1);

    byte[] datas = new byte[1024];

    int j = 0;

    while ((j = fin.read(datas)) > 0) {

        out1.write(datas);

        fin.read(datas);

    }

    fin.close();
    out1.close();

反序列化：
使用ObjectInputStream()
FileInputStream fis = new FileInputStream("D:/2.txt");
ObjectInputStream oin = new ObjectInputStream(fis);
oin. readObject();
錯誤：Exception in thread "main" java.io.StreamCorruptedException: invalid stream header: 3139322E
該怎麼處理？
如果檔案較大，讀入時加入快取該怎麼寫？望大牛賜教，xiexie
