第四次考核

码云地址：https://gitee.com/x-alchemist/java_study/tree/master/Exercise4

使用套接写连接编写一个简单的聊天室程序，客户端主函数放在Client_Main.java文件中，服务器端主函数放在Server_Main.java文件中

   要求：

    　　   1.客户端从控制台进行输入，并将客户端的输出内容和时间保存到“学号.txt”文件中

      　　 2.服务器端读取到客户端的程序后，给客户端以回应，并将客户端的输入内容与服务端的输出内容、时间保存到文本文件中

    　　   3.要求服务器端可以实现同时与多个客户端进行通信，与每一个客户端通信的内容，保存为一个“学号_ip.txt”的文件

　　　　4..提交文件结果包括：代码，通信后生成的txt文件
