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();
}
}
}
