Java-I/O框架05：通过集合对多个对象序列化和反序列化

1.通过集合实现多个对象序列化

public class ObjectOutputStreamDemo02 {
    public static void main(String[] args) throws Exception {
        //创建对象输出流

        FileOutputStream fos = new FileOutputStream("C:\\Users\\Public\\Documents\\hhh.txt");
        ObjectOutputStream oos = new ObjectOutputStream(fos);

        //实例化对象，创建1个ArrayList数组，把对象添加到数组中

        Student s1 = new Student("刘德华", 20);
        Student s2 = new Student("张学友", 19);
        Student s3 = new Student("林志玲", 21);

        ArrayList<Student> students = new ArrayList<>();

        students.add(s1);
        students.add(s2);
        students.add(s3);

        //将对象输出到文件（序列化过程）
        oos.writeObject(students);

        //关闭流通道
        oos.close();
        System.out.println("序列化执行完毕");

    }
}

2.通过集合实现多个对象反序列化

public class ObjectInputStreamDemo02 {
    public static void main(String[] args) throws Exception {

        //1.创建对象输出流
        FileInputStream fis = new FileInputStream("C:\\Users\\Public\\Documents\\hhh.txt ");
        ObjectInputStream ois = new ObjectInputStream(fis);

        //读取对象文件

        ArrayList<Student> s = (ArrayList<Student>) ois.readObject();
        System.out.println(s.toString());

        //关闭
        ois.close();
        System.out.println("反序列化执行完毕");
    }
}
