9月27 对象序列化和反序列化基本实现流程

1 必须实现Serializable, 才可序列化！！先学实现这个接口。

//对象序列化例子

import java.io.*;

public class Objectse
{
public static void main(String[] args)throws Exception
{
Persion p = new Persion("邹阳");

//开始对Persion进行序列化

File f = new File("D:\\Persion.txt");

FileOutputStream fos = new FileOutputStream(f);

ObjectOutputStream oos = new ObjectOutputStream(fos);

oos.writeObject(p);

oos.close();

//反序列化，反序列化之后对Persion对象进行操作

FileInputStream fis = new FileInputStream(f);

ObjectInputStream ois = new ObjectInputStream(fis);

Persion persion = (Persion)ois.readObject();
System.out.println(persion.name);

ois.close();

}
}

//必须实现接口才能序列化
class Persion implements Serializable
{
public Persion(String name)
{
this.name = name;
}

public String name;
}
