如何对Java对象(类)进行编码和重新解码？

import java.io.*;

public class SerializationExample {
    public static void main(String[] args) {
        // 创建一个Java对象
        Person person = new Person("Alice", 25);

        // 序列化对象
        try {
            FileOutputStream fileOut = new FileOutputStream("person.ser");
            ObjectOutputStream out = new ObjectOutputStream(fileOut);
            out.writeObject(person);
            out.close();
            fileOut.close();
            System.out.println("对象已序列化");
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 反序列化对象
        try {
            FileInputStream fileIn = new FileInputStream("person.ser");
            ObjectInputStream in = new ObjectInputStream(fileIn);
            Person deserializedPerson = (Person) in.readObject();
            in.close();
            fileIn.close();
            System.out.println("对象已反序列化");
            System.out.println("姓名：" + deserializedPerson.getName());
            System.out.println("年龄：" + deserializedPerson.getAge());
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}

class Person implements Serializable {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }
}
