• java的序列化是將對(duì)象寫入到文本中
• 首先需要一個(gè)類,必須實(shí)現(xiàn)Serializable接口

class Person implements Serializable{
    //如果這個(gè)屬性不想被序列化就加上transient
    transient int age;  
    String name;
}

• 下邊是寫入的代碼

        //寫入
        FileOutputStream fileOut = new FileOutputStream("out.txt");
        ObjectOutputStream stream = new ObjectOutputStream(fileOut);
        Person p = new Person();
        p.age = 12;
        p.name = "張三";
        stream.writeObject(p);
        stream.close();
        fileOut.close();

        //讀取出來
        FileInputStream file = new FileInputStream("out.txt");
        ObjectInputStream stream = new ObjectInputStream(file);
        Object object = stream.readObject();
        Person p = (Person)object;
        System.out.println("name = " + p.name);
        System.out.println("age = " + p.age);
        stream.close();
        file.close();
