java序列化学习笔记

待序列化的类 实现Serializable接口

package test.java;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectInput;import java.io.ObjectInputStream;import java.io.ObjectOutput;import java.io.ObjectOutputStream;public class MySerialization {/** * @param args */public static void main(String[] args) {String filePath="d:\\user.txt";User user=new User();user.setId(1);user.setName("zhangsan");user.setAge(22);writeUser(user, filePath);User user1=readUser(filePath);System.out.println(user1.getId());System.out.println(user1.getName());System.out.println(user1.getAge());}public static void writeUser(Object object,String filePath){ObjectOutputStream objectOutputStream=null;try {objectOutputStream=new ObjectOutputStream(new FileOutputStream(new File(filePath)));objectOutputStream.writeObject(object);} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}finally{try {objectOutputStream.close();} catch (IOException e) {e.printStackTrace();}}}public static User readUser(String filePath){ObjectInputStream objectInputStream=null;User user=null;try {objectInputStream=new ObjectInputStream(new FileInputStream(new File(filePath)));user=(User)objectInputStream.readObject();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (ClassNotFoundException e) {e.printStackTrace();}finally{try {objectInputStream.close();} catch (IOException e) {e.printStackTrace();}}return user;}}

如果让别的机子来读取(readObject)user.txt文件，是否能成功读取用户的信息？
