Java 文本冒险游戏保存到文件，但当我试图加载它停止程序

我相信这就是所有相关的代码。我很抱歉，如果我把不相关的代码，我会删除任何不需要的。我找到了如何编码来保存和加载这个网站，但我不知道如何让它真正加载我的游戏。非常感谢您的帮助。您似乎没有在写入文件后关闭文件。尝试在oos之后添加oos.close，或将其替换为oos.flushI。我不确定是否可以将多个对象保存到一个文件中。无论哪种方式，都可以使用一个从文件中写入/读取的可序列化对象SavedGame。随机提示：静态保存调用Player.setUserName，但加载调用p.getUserName。应该使用其中一种。谢谢你的评论。玩过之后，我让它正常工作了。
