序列化是一种将对象以一连串的字节描述的过程，用于解决在对对象流进行读写操作时所引发的问题。那么什么情况下需要使用序列化呢？

1、需要通过网络来发送对象，或对象的状态需要被持久化到数据库或文件中。

2、序列化能实现深复制，即可以复制引用的对象。

package hanjia;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 People implements Serializable{private static final long serialVersionUID = 1L;public String name;public int age;public People(){this.name = "ali";this.age = 20;}public static void main(String[] args) {try {FileOutputStream fos = new FileOutputStream("people.out");ObjectOutputStream oop = new ObjectOutputStream(fos);oop.writeObject(new People());oop.close();FileInputStream fis = new FileInputStream("people.out");ObjectInputStream ois = new ObjectInputStream(fis);People p = (People)ois.readObject();ois.close();System.out.println(p.name);} catch (FileNotFoundException e) {System.out.println("ss");e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (ClassNotFoundException e) {e.printStackTrace();}}}
