[java]:对象序列化非常简单能看懂的操作

就看这个绝对能看懂！！！！

import java.io.*;
import java.util.Date;

public class ObjectSaver {
    public static void main(String[] args) throws Exception {
        /*其中的  D:\\objectFile.obj 表示存放序列化对象的文件*/

        
        //序列化对象
        ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("D:\\objectFile.obj"));
        Customer customer = new Customer("王麻子", 24);    
        out.writeObject("你好!");    //写入字面值常量
        out.writeObject(new Date());    //写入匿名Date对象
        out.writeObject(customer);    //写入customer对象
        out.close();

        
        //反序列化对象
        ObjectInputStream in = new ObjectInputStream(new FileInputStream("D:\\objectFile.obj"));
        System.out.println("obj1 " + (String) in.readObject());    //读取字面值常量
        System.out.println("obj2 " + (Date) in.readObject());    //读取匿名Date对象
        Customer obj3 = (Customer) in.readObject();    //读取customer对象
        System.out.println("obj3 " + obj3);
        in.close();
    }
}

class Customer implements Serializable {
    private String name;
    private int age;
    public Customer(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String toString() {
        return "name=" + name + ", age=" + age;
    }
}
