[Java基础]对象(反)序列化流

Posted 2021-06-26 Wecccccccc

对象序列化流:
代码如下:

package ObjectOutputStreamPack;

import java.io.Serializable;

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

    public Student() {
    }

    public Student(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;
    }
}

package ObjectOutputStreamPack;

import java.io.*;

public class ObjectOutputStreamDemo
{
      public static void main(String[] args) throws IOException {
          ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("D:\\\\JavaDemo\\\\oos.txt"));

            Student s = new Student("Tom",33);

            oos.writeObject(s);

            oos.close();
      }

}

对象反序列化流:
代码如下:

package ObjectOutputStreamPack;

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

public class ObjectInputStreamDemo {
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        ObjectInputStream ois = new ObjectInputStream(new FileInputStream("D:\\\\JavaDemo\\\\oos.txt"));

          Object obj = ois.readObject();
          Student s = (Student)  obj;
          System.out.println(s.getName()+","+s.getAge());

          ois.close();
    }

}
