我有一些java序列化代码。它编译并正常运行。但生成的文件是空的。下面是我的代码

参数是整数数组列表、字符串数组列表或整数数组列表数组列表

Model model = new Model(
    pennTreeTags,
    tagsCount,
    iOccurTable,
    fOccurTable,
    alVocab,
    aiVocabCount,
    wordTagTable,
    fWordTagProb
);

try 
{
    FileInputStream fileIn = new FileInputStream(argv[2]);
    ObjectInputStream in = new ObjectInputStream(fileIn);
    model = (Model) in.readObject();
    in.close();
    fileIn.close();
}
catch (EOFException ex) 
{ 
    //This exception will be caught when EOF is reached
    System.out.println("End of file reached.");
}
catch(IOException i)
{
    i.printStackTrace();
    return;
}
catch(ClassNotFoundException c)
{
    System.out.println("Model class not found");
    c.printStackTrace();
    return;
}

您没有向任何文件写入任何内容。您只是从文件中读取。如果要写入文件，请使用 *Output*Stream。
