从独立类

Question

我的问题是关于反序列化使用一个类创建的文件＆＃34;字符＆＃34;和一个GUI表格＆＃34; NewChar＆＃34;。

我对Java相对较新，并尝试创建DnD样式字符生成器。我目前正在使用三个类 - Character（包含名称，性别，类，str，dex等实际统计信息的java类），其中包含构造函数;一个GUI表单（NewChar，使用NetBeans和Swing创建），允许用户选择Character类中定义的统计数据并根据需要自定义它们;和CharMain GUI页面应该（最终）向用户显示他们的角色并允许他们升级，选择武器等。

到目前为止，我可以通过在NewChar GUI框架中实例化类Character来成功地序列化数据（据我所知）。我还是无法从CharMain GUI页面加载序列化文件。首先，当我尝试readObject（）时，问题似乎是ClassNotFoundException;在我尝试序列化的任何字符串上。其次，我继续收到EOF异常，虽然我怀疑这是因为序列化然后反序列化的项目数量自readObject（）以来没有匹配;不工作。我用Google搜索并搜索了StackOverFlow并找到了一些针对类似问题的回复（例如：readobject method throws ClassNotFoundException或Java Mysterious EOF exception with readObject），但无法针对我的回复做出正面或反面的回答情况。

我曾尝试将我的Character类复制并粘贴到两个GUI表单中，但这似乎没有帮助。我还尝试仅序列化类Character的实例（实例名为createdChar），但这似乎也没有帮助。

我知道我试图反序列化的对象需要匹配已经序列化的对象（即包，类名等），但据我所知。我可能是超级盲人和/或愚蠢的忘记，但我的内部同事编码器似乎也无法弄清楚。在这一点上，我正在考虑将信息写入文本文件并将其读回而不是使用ObjectOutputStream和ObjectInputStream，但仍然真的想知道为什么这不起作用。请帮忙！

以下是序列化（然后反序列化）数据的代码：

private void viewCharActionPerformed(java.awt.event.ActionEvent evt) {                                         
    // TODO add your handling code here:
    String fileName = String.valueOf(createdChar.charName);
    try {
        FileOutputStream charSave = new FileOutputStream("/C:\\javaSaves\\newChar.sav");
        ObjectOutputStream out = new ObjectOutputStream(charSave);

        out.writeObject(createdChar.str);
        out.writeObject(createdChar.dex);
        out.writeObject(createdChar.con);
        out.writeObject(createdChar.intel);
        out.writeObject(createdChar.wis);
        out.writeObject(createdChar.charisma);
        out.writeObject(createdChar.strMod);
        out.writeObject(createdChar.dexMod);
        out.writeObject(createdChar.conMod);
        out.writeObject(createdChar.intelMod);
        out.writeObject(createdChar.wisMod);
        out.writeObject(createdChar.charisMod);
        out.writeObject(createdChar.baseAttack);
        out.writeObject(createdChar.reflexSave);
        out.writeObject(createdChar.willSave);
        out.writeObject(createdChar.fortSave);
        out.writeObject(createdChar.hp);
        out.writeObject(createdChar.lvl);
        out.writeObject(createdChar.speed);
        out.writeObject(createdChar.armorClass);
        out.writeObject(createdChar.size);
        out.writeObject(createdChar.charName);
        out.writeObject(createdChar.charRace);
        out.writeObject(createdChar.charClass);
        out.writeObject(createdChar.gender);

        out.close();
        charSave.close();
        System.out.printf("Serialized data is saved on C:\\javaSaves\\newChar.sav");
   }
    catch (IOException i) {
        i.printStackTrace();
    }

        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new charMain().setVisible(true);
            }
        });

        closeFrame();
}  

public void loadCharacterFromFile(){
    try {
        FileInputStream saveFile = new FileInputStream("/C:\\javaSaves\\newChar.sav");
        ObjectInputStream save = new ObjectInputStream(saveFile);
            createdChar.str = save.readInt();
            createdChar.dex = save.readInt();
            createdChar.con = save.readInt();
            createdChar.intel = save.readInt();
            createdChar.wis = save.readInt();
            createdChar.charisma = save.readInt();
            createdChar.strMod = save.readInt();
            createdChar.dexMod = save.readInt();

            createdChar.fortSave = save.readInt();
            createdChar.hp = save.readInt();
            createdChar.lvl = save.readInt();
            createdChar.speed = save.readInt();
            createdChar.armorClass = save.readInt();
            createdChar.size = (String) save.readObject();
            createdChar.charName = (String) save.readObject();    
            createdChar.charRace = (String) save.readObject();
            createdChar.charClass = (String) save.readObject();
            createdChar.gender = (String) save.readObject();
