要求：

基于TCP協(xié)議實(shí)現(xiàn)，客服端向服務(wù)器發(fā)送一個(gè)對(duì)象 服務(wù)器接受并顯示用戶信息 ，同時(shí)返回給客戶端 "數(shù)據(jù)已收到"建一個(gè)Student類，屬性：name age

Student類

package Homework3;import java.io.Serializable;public class Student implements Serializable {private static final long serialVersionUID = 1L;private String name;private int age;private String sex;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 String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}@Overridepublic String toString() {return "Student [name=" + name + ", age=" + age + ", sex=" + sex + "]";}public Student(String name, int age, String sex) {super();this.name = name;this.age = age;this.sex = sex;}public Student() {super();}}

客戶端：
