写入Student对象到Student.txt

public class WriterStudent {    public static void main(String[] args) {        try {            ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("Student.txt"));            Student stu1 = new Student("徐恺",19);            Student stu2 = new Student("路娟娟",18);            Student stu3 = new Student("崔亚涛",20);            oos.writeObject(stu1);            oos.writeObject(stu2);            oos.writeObject(stu3);            //写入结束标志方便读取（非常重要，如果不写入，在读取的时候无法定位读取结束）；            oos.writeObject(null);            oos.close();        }catch (IOException e) {            e.printStackTrace();        }    }}

读取Student对象到console

public class ReaderStudent {    public static void main(String[] args) {        ObjectInputStream ois = null;        try {            ois = new ObjectInputStream(new FileInputStream("Student.txt"));            try {                Student s = null;                while(true){                    if((s = (Student)ois.readObject()) != null){                        s.showInfo();                    }else{                        break;                    }                }            } catch (ClassNotFoundException e) {                e.printStackTrace();            }            ois.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

序列化Student类

package com.lanou3g.job11;import java.io.Serializable;public class Student implements Serializable{    private String name;    private int age;    public Student() {        super();    }    public Student(String name, int age) {        super();        this.name = name;        this.age = age;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public int getAge() {        return age;    }    public void setAge(int age) {        this.age = age;    }    public void showInfo(){        System.out.println("姓名:" + name + ",年龄" + age);    }}
