java - 在 .readObject() 上找不到符号；

Question

我在加载保存文件时遇到问题，它在 2 个 int 变量的 .readObject() 中显示“找不到符号”错误。我正确声明了变量，并且这两个变量都是全局变量。我不知道为什么。我试图寻找答案，所以我最终来到了这里。提前 ty 伙计们

public void loadGame()
{
    //Load Game
    try
    {
        FileOutputStream saveFile = new FileOutputStream("save.txt");
        ObjectOutputStream load = new ObjectOutputStream(saveFile);
        cursortrigger = (Integer) load.readObject();
        soundtrigger = (Integer) load.readObject();
        load.close();   
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

}
public void saveGame()
{
    //Save Game
    try
    {
        FileOutputStream saveFile = new FileOutputStream("save.txt");
        ObjectOutputStream save = new ObjectOutputStream(saveFile);
        save.writeObject(cursortrigger);
        save.writeObject(soundtrigger);
        save.close();   
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

}

Answer 1

FileOutputStream saveFile = new FileOutputStream("save.txt");
ObjectOutputStream load = new ObjectOutputStream(saveFile);

这是错误的。要读取对象，您需要ObjectInputStream和FileInputStream。

FileInputStream saveFile = new FileInputStream("save.txt");
ObjectInputStream load = new ObjectInputStream(saveFile);
