本文展示了一个使用Java进行对象序列化和反序列化的简单示例。通过将Person类的对象写入文件并从文件中读取，演示了如何利用ObjectOutputStream和ObjectInputStream实现这一过程。

import java.io.*;

class ObjectInputStreamDemo
{
    public static void main(String[] args) throws Exception
    {
        String fileName = "obj.txt";
        writer(fileName,new Person("陈晓明",28));
        Person person = reader(fileName);

        System.out.println(person.toString());
    }

    public static Person reader(String fileName) throws Exception
    {
        ObjectInputStream ois = new ObjectInputStream(new FileInputStream(new File(fileName)));
        Person person = (Person)ois.readObject();
        ois.close();

        return person;
    }

    public static void writer(String fileName,Person person)  throws Exception
    {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(new File(fileName)));
        oos.writeObject(person);
        oos.close();
    }
}

class Person implements Serializable
{
    public static final long serialVersionUID = 42L;

    String name;
    int age;

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

    public String toString()
    {
        return (this.name + "::" + this.age);
    }
}
