Java序列化反序列化对象流ObjectInputStream、ObjectOutputStream

使用**Person**类作为Object进行示范

注意:**Object**要能被写入流需要实现**Serializable**接口

存储的文件后缀名为**.ser**

示范**Person**类

import java.io.Serializable;

public class Person implements Serializable\{  
private static final long serialVersionUID = 1L;  
String name;  
int age;  
boolean sex;//true means male false means female  
Person(String name,int age,boolean sex)  
\{  
this.name=name;  
this.age=age;  
this.sex=sex;  
\}  
void print()  
\{  
System.out.println("姓名:"+name);  
System.out.println("年纪:"+age);  
System.out.println("性别:"+sex);  
\}  
\}

**将Person对象序列化存储到文件**

示范Serializable\_Test 类

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

public class Serializable\_Test \{

public static void main(String\[\] args) \{  
try \{  
Person p=new Person("张三",18,true);  
File f=new File("D:\\\\objecttest.ser");  
FileOutputStream fos=new FileOutputStream(f);  
ObjectOutputStream oos=new ObjectOutputStream(fos);  
oos.writeObject(p);  
oos.close();  
fos.close();  
\} catch (Exception e) \{  
e.printStackTrace();  
\}  
\}  
\}

**从文件中读取对象，反序列化Deserializable**

示范Deserializable\_Test类

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

public class Deserializable\_Test \{

public static void main(String\[\] args) \{  
try \{  
File f=new File("d:\\\\objecttest.ser");  
FileInputStream fis=new FileInputStream(f);  
ObjectInputStream ois=new ObjectInputStream(fis);  
Person p=(Person)ois.readObject();  
p.print();  
\} catch (Exception e) \{  
e.printStackTrace();  
\}  
\}  
\}
