摘要
当我尝试序列化我的匿名函数（包括一个方法）时 - 它似乎没有正确地序列化它。
问题
我有一个接口：Program，它实现Serializable并包含函数void run();我的main方法创建一个变量：p并使其为Program类型
To＆＃34;初始化＆＃34;这个，我为界面创建了一个匿名类。其中有run()方法。我输入了这个：System.out.println("Hello world, this is a test");
我有另一个类ProgramIO，它使用ObjectOutput和ObjectInput个流来读取和写入文件。
写作成功，阅读也是如此 - 直到我从ProgramIO开始阅读它（from: Program p = new Program {...} to Program p = ProgramIO.readProgram(...)}当它是这样的时候 - 阅读和写作都不起作用。（写作不应该＆＃39;但是阅读应该）
这是错误：java.lang.ClassNotFoundException: Main$2
假设
我相信这个问题正在发生，因为它正在寻找主类中的代码。这就是为什么我想知道如何解决这个问题。
代码

os.writeObject(d);
os.close();
e.close();
} catch (IOException var4) {
var4.printStackTrace();
}
}
