Serializable方法

package com.neusoft.test1; //首先定义一个被序列化的类
import java.io.Serializable;
class Student implements Serializable {// 定义一个可以被序列化的类
 String name;
int age;
 String num;
double score;
public Student() {
 }
public Student(String name, int age, String num, double score) {
this.name = name;
this.age = age;
this.num = num;
this.score = score;
 }
public String toString() {
return name + "\t" + age + "\t" + num + "\t" + score;
 }
}

定义一个用于将Student对象序列化的类

package com.neusoft.test1;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
publicclass SerializableTest {
publicstaticvoid main(String[] args) {
 Student stu_1 = new Student("wjl", 25, "47843847", 89);// 实例化两个可以被序列化的student对象
 Student stu_2 = new Student("yxm", 23, "47856547", 99);
 File f = new File("c:/demo/456.txt");// 保存两个对象的文件对象
try {
 FileOutputStream fos = new FileOutputStream(f);
 ObjectOutputStream oos = new ObjectOutputStream(fos);
 System.out.println("没有被序列化时的对象如下：");
 System.out.println(stu_1);
 System.out.println(stu_2);
 oos.writeObject(stu_1);
 oos.writeObject(stu_2);
 System.out.println("序列化成功！！");
 oos.flush();
 fos.close();
 oos.close();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
}

定义一个用于将Student对象反序列化的类

package com.neusoft.test1;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
publicclass TurnSerializableTest {
publicstaticvoid main(String[] args) {
 File f = new File("c:/demo/456.txt");
try {
 FileInputStream fis = new FileInputStream(f);
 ObjectInputStream ois = new ObjectInputStream(fis);
 Student stu_1;
 stu_1 = (Student) ois.readObject();
 System.out.println(stu_1);
 Student stu_2 = (Student) ois.readObject();
 System.out.println(stu_2);
 fis.close();
 ois.close();
 } catch (ClassNotFoundException e) {
 e.printStackTrace();
 } catch (IOException e) {
 e.printStackTrace();
 }
 }
}
