JAVA开发进阶实验报告模板

1、java开发进阶实验报告实验序号：4 实验项目名称：套接字通信学号1221145123姓名何征专业、班12软件工程实验地点实1-518指导教师唐朝辉实验时间2013.3.26一、实验目的及要求了解套接字通信并且熟悉输入流、输出流得操作同时掌握套接字编程二、实验设备（环境）及要求windows 操作系统；Eclipse PC计算机三、实验内容与步骤1. 请看例子4-2。2. 请看例子4-4。四、实验结果与数据处理五、分析与讨论编写的过程当中，客户端和服务端经常出现系统崩溃，后来才发现是编写的代码出现了问题，导致使用不了，后来在努力查找下终于实现了运行。第二个实验也是，比较多的问题都是代码出错，表

2、示写得有点纠结，不过之后经过修改就成功了。发现细心很重要。六、教师评语签名：日期：成绩列出程序代码：一（1）、import java.io.*;import .*;import .Socket;public class ServerThread extends Thread private Socket connectToClient;private DataInputStream inFromClient;private DataOutputStream outToClient;public ServerThread(Socket socket) throws IOExceptionsupe
