逆シリアル化関数を使用して Java でオブジェクトのシリアル化と逆シリアル化を実装する方法

import java.io.Serializable;

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

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

    // getter and setter
}

import java.io.FileOutputStream;
import java.io.ObjectOutputStream;

public class SerializationDemo {
    public static void main(String[] args) {
        Person person = new Person("张三", 25);

        try {
            FileOutputStream fileOut = new FileOutputStream("person.ser");
            ObjectOutputStream out = new ObjectOutputStream(fileOut);
            out.writeObject(person);
            out.close();
            fileOut.close();
            System.out.println("对象已被序列化并保存在person.ser文件中");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

import java.io.FileInputStream;
import java.io.ObjectInputStream;

public class DeserializationDemo {
    public static void main(String[] args) {
        Person person = null;

        try {
            FileInputStream fileIn = new FileInputStream("person.ser");
            ObjectInputStream in = new ObjectInputStream(fileIn);
            person = (Person) in.readObject();
            in.close();
            fileIn.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

        if (person != null) {
            System.out.println("对象已经从person.ser文件中反序列化：" + person.getName() + "，" + person.getAge());
        }
    }
}
