java 序列化 与 反序列化 demo

import java.io.*;

    // 不让反序列化 ,该值为类型的默认值
    private String name;
    private transient int age;

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

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

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

        ser(new Person("小张", 18));
        dser();
    }

    public static void ser(Person person) throws Exception {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("d:" + File.separator + "1.txt"));
        oos.writeObject(person);
        oos.close();
    }
