已知函数getStudent()定义为public Student getStudent(int ID)，下列四个选项中可以与getStudent构成重载的方法是 A: private Student getStudent(int ID) B: public String getStudent(int ID) C: Student getStudent(String name) D: public Student get(int ID)

一． IO操作问题描述程序功能：在网络传输过程中，对象数据往往需要进行序列化操作，即将对象序列化为byte数组，同时也需要反序列化操作将byte数组转化为对象。下面程序中定义了一个Student类，在该类中已经实现了反序列化操作，请完成序列化的操作代码。程序结构如下：import java.io.*;class Student{int stuNo;//学号String name;//姓名String sex;//性别int age;//年龄String grade;//年级String classname;//班级public Student(int stuNo,String name,String sex,int age,String grade,String classname){this.stuNo=stuNo;this.name=name;this.sex=sex;this.age=age;this.grade=grade;this.classname=classname;}//反序列化操作public static Student GetStudent(byte[] byteStudent){try{ByteArrayInputStream bais=new ByteArrayInputStream(byteStudent);DataInputStream dis=new DataInputStream(bais);int stuNo=dis.readInt();String name=dis.readUTF();String sex=dis.readUTF();int age=dis.readInt();String grade=dis.readUTF();String classname=dis.readUTF():return new Student(stuNo,name,sex,age,grade,classname);}catch(Exception ex){return null;}//序列化操作，请完成public byte[] GetBytes(){... //补充此处代码}public class Exam2{public static void main(String args[]){Student stu=new Student(20090223,”jack”,”man”,21,”三年级”,”2班”);byte[] bytestu=stu.GetBytes();Student stu1=Student.GetStudent(bytestu);System.out.println(stu1.s5uNo);}程序要求1. 实现序列化代码
