最近在准备面试，复习java基础知识，记录一下Java对象的序列化：

Java对象的序列化：要想实现序列化，需要把被序列化的对象（类）实现Java.io.Serializable接口，配合FileOutputStream、FileInputStream、FileOutputStream、FileInputStream实现把对对象数据转换成二进制流存储到字旁的固定文件上，再把他读进来

代码演示：

package cn.com.test;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.io.Serializable;public class SerializableTest {public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException  {SerializableTest.Serialize();SerializableTest.deSerialize();}public static void deSerialize() throws FileNotFoundException, IOException, ClassNotFoundException{ObjectInputStream in = new ObjectInputStream(new FileInputStream("F:\\test.txt")) ;//读取HelloSystem.out.println((String)in.readObject());//读取personSystem.out.println((Person)in.readObject());in.close();}public static void Serialize() throws FileNotFoundException, IOException{ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("F:\\test.txt")) ;out.writeObject("Hello!");out.writeObject(new Person("张剑飞", 22));out.close() ;}}@SuppressWarnings("serial")class Person implements Serializable {private String name ;private int age ;public Person(String name, int age) {this.name = name;this.age = age;}@Overridepublic String toString() {return "Person [name=" + name + ", age=" + age + "]";}}
