[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;
}
}
