ObjectOutputStream—ObjectInputStream序列化和反序列化

Person

import java.io.Serializable;//起到标记作用

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

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }

    public Person() {
    }

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

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

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

 

 

ObjectOutputStream

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;

public class Demo01ObjectOutputStream {
    public static void main(String[] args) throws IOException {
        ObjectOutputStream oos=new ObjectOutputStream(new FileOutputStream("F:\\basic\\untitled13\\src\\it\\cast\\day15\\demo06\\1.txt"));
        oos.writeObject(new Person("美女",18));
        oos.close();

    }

}

 

ObjectInputStream

import java.io.FileInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;

public class Demo02ObjectInputStream {
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        ObjectInputStream ois=new ObjectInputStream(new FileInputStream("F:\\basic\\untitled13\\src\\it\\cast\\day15\\demo06\\1.txt"));
        Object object = ois.readObject();
        ois.close();
        System.out.println(object);
        Person p = (Person) object;
        System.out.println(p.getName()+"="+p.getAge());

    }
}
