java - 在可序列化编程中收到错误 “cannot find symbol”

Question

我收到此错误:

Error:(5, 9) java: cannot find symbol
  symbol:   class Employee
  location: class Student
Error:(5, 24) java: cannot find symbol
  symbol:   class Employee
  location: class Student

嗨，我正在用Java编写一个可序列化的程序，但这给了我这个错误，请您解决一下并告诉我这是什么问题吗？

帮助将不胜感激!

这是我的源代码:

import java.io.*;

public class Student{
    public static void main(String[] args) throws Exception{
        Employee e=new Employee(221, "My name is Rajendra Arora");

        FileOutputStream fout=new FileOutputStream("D://raj1.txt");
        ObjectOutputStream out=new ObjectOutputStream(fout);

        out.writeObject(e);
        out.flush();

        System.out.println("Success....");
    }
}

确保Java文件都在同一目录中

例如:

myDirectory/Employee.java
myDirectory/Student.java
