Question

这是我正在序列化的文件Employee.java：

import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import java.util.Date;

public class Employee implements Externalizable {
String lName;
String fName;
double salary;
String address;
Date hireDate;
int id;
@Override
public void writeExternal(ObjectOutput out) throws IOException {
    // TODO Auto-generated method stub
    out.writeDouble(salary);
    out.writeInt(id);
}
@Override
public void readExternal(ObjectInput in) throws IOException,
        ClassNotFoundException {
    // TODO Auto-generated method stub
    salary= in.readDouble();
    id= in.readInt();
} 
}

这是我实际序列化的代码

 import java.io.*;
 import java.util.Date;
 public class ClassA {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    Employee emp= new Employee();
    emp.salary= 2000;
    emp.id= 234;
    FileOutputStream fos= null;
    ObjectOutput oos= null;
    try{
        fos= new FileOutputStream("C:\\dkbexternalizable.ser");
        oos= new ObjectOutputStream(fos);
    //  oos.writeObject(emp);
        emp.writeExternal(oos);
        oos.flush();
    }
    catch(IOException e){
        try {
            oos.close();
            fos.close();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }
    System.out.println("The employee object has been serialized into "+"C:\\dkbexternalizable.ser");
    }

}

当我调试上面的序列化代码时，我看到0.0和0是为.ser文件中的salary和id值传递的。我希望将2000和234传递给他们。有一些基本的错误，我无法弄清楚。有人可以帮帮我吗？

序列化对象时不传递正确的值
