反序列化

如下代码：person是可以序列化的类

Person.java
package com.company;

import java.io.Serializable;

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

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

    }

    public void setname(String name) {
        this.name = name;
    }

    public String getname() {
        return name;

    }

    public void setAge(int age) {
        this.age = age;

    }

    public int getAge() {
        return age;

    }

    public void setAdress(String adress) {
        this.adress = adress;
    }

    public String getAdress() {
        return adress;
    }

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


}
将person 对象进行序列化保存到文件

package com.company;

import java.io.*;

public class Main {

    public static void main(String[] args) {
   // write your code here
        try(//（将序列化后的对象）输出到文件中
            ObjectOutputStream obs= new ObjectOutputStream(new FileOutputStream("D:\\练习.txt")))
        {
            Person person =new Person("钰钰",10,"赵庄");
            obs.writeObject(person);
            obs.flush();
            System.out.println("YEs");
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

package com.company;
//反序列化
import java.io.*;
public class ObjectInputStreamDemo {


    public  static void main(String args[])
    {
        //往程序中输入
        try(ObjectInputStream ois=new ObjectInputStream(new FileInputStream("D:\\练习.txt")))
        {
            Person person=(Person)ois.readObject();//强制将序列化后的对象呈现到程序中
            System.out.println(person);
        }catch(Exception ex)
        {
            ex.printStackTrace();
        }
    }
}
