Java 对象序列化与反序列化：使用 ObjectOutputStream 和 ObjectInputStream

import java.io.*;

public class Main { public static void main(String[] args) throws IOException, ClassNotFoundException { Student s = new Student(10, 'Lily'); // 创建文件输出流对象，将数据写入student.txt文件 FileOutputStream fos = new FileOutputStream("src/student.txt"); // 创建对象输出流对象 ObjectOutputStream oos = new ObjectOutputStream(fos); oos.writeObject(s); oos.close();

    // 创建文件输入流对象，读取student.txt文件的内容
    FileInputStream fis = new FileInputStream("src/student.txt");
    ObjectInputStream ois = new ObjectInputStream(fis);
    // 从student.txt文件中读取数据
    Student s1 = (Student) ois.readObject();
    System.out.println("Student对象的id是  ：" + s1.getId());
    System.out.println("Student对象的name是：" + s1.getName());
    ois.close();
}

}

class Student implements Serializable { private int id; private String name;

public Student(int id, String name) {
    this.id = id;
    this.name = name;
}

public int getId() {
    return id;
}

public String getName() {
    return name;
}

}
