序列化响应Android Studio中的所有字段？

public class Response implements Serializable {
    // 类的字段和方法
}

Response response = new Response();
// 设置response的字段值

try {
    FileOutputStream fileOut = new FileOutputStream("response.ser");
    ObjectOutputStream out = new ObjectOutputStream(fileOut);
    out.writeObject(response);
    out.close();
    fileOut.close();
    System.out.println("序列化成功");
} catch (IOException e) {
    e.printStackTrace();
}

try {
    FileInputStream fileIn = new FileInputStream("response.ser");
    ObjectInputStream in = new ObjectInputStream(fileIn);
    Response response = (Response) in.readObject();
    in.close();
    fileIn.close();
    System.out.println("反序列化成功");
} catch (IOException | ClassNotFoundException e) {
    e.printStackTrace();
}
