对象序列化 代码

 Student.java

package ZHANG.IO.Serialization;import java.io.Serializable;public class Student implements Serializable {int id;String name;int age;String department;public Student(int id, String name, int age, String department) {this.id = id;this.name = name;this.age = age;this.department = department;}}

 

Serialization.java

package ZHANG.IO.Serialization;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;public class Serialization {public static void main(String[] args) {Student stu1 = new Student(21,"zhangsan",25,"computer");Student stu2 = new Student(22,"baiyan",22,"huaxue");try {FileOutputStream fos = new FileOutputStream("student.txt");ObjectOutputStream os = new ObjectOutputStream(fos);os.writeObject(stu1);os.writeObject(stu2);os.close();FileInputStream fis = new FileInputStream("student.txt");ObjectInputStream ois = new ObjectInputStream(fis);stu1 = (Student) ois.readObject();stu2 = (Student) ois.readObject();System.out.println("student1 details:"+stu1.name+" "+stu1.age+" "+stu1.id+" "+stu1.department);System.out.println("student2 details:"+stu2.name+" "+stu2.age+" "+stu2.id+" "+stu2.department);} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (ClassNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

===========

private transient String name;   //不需要被序列化 加transient=-=-=

另一个列子：

package com.serDemo;import java.io.Serializable;public class Person implements Serializable{private String name; //不需要被序列化 加transientprivate int age;public Person(String name, int age) {super();this.name = name;this.age = age;}@Overridepublic String toString() {return "姓名:"+name+",年龄:"+age;}}

package com.serDemo;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectOutputStream;public class ObjectoutputStreamDemo {public static void main(String[] args) throws Exception, IOException {File file = new File("d://person.ser");ObjectOutputStream oos = null;oos = new ObjectOutputStream(new FileOutputStream(file));Person p = new Person("战士12",34);oos.writeObject(p);oos.close();} }

 

package com.serDemo;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;public class ObjectInputStreamDemo {public static void main(String[] args) throws Exception, IOException {File file = new File("d://person.ser");ObjectInputStream ois = null;ois = new ObjectInputStream(new FileInputStream(file));Person p =(Person)ois.readObject();System.out.println(p);} }

//对一组对象进行序列化
