花旗的面试，有面试题目（其中包含英文面试题目）、笔试、因为包含了个CoreJava的面试题目，所以就选择了Java类了(Citigroup interview, interview questions (which contains the English interview questions), written, because contains a CoreJava the interview questions, so we chose Java class)

B curve left key point, right end vevr good(Curve B left key point, right end vevr good)

一个用Sockets实现的简单通信：首先运行ASCIIServer.java再运行ASCIIClient.java。然后客户端会发送65-90到服务端，并在服务端翻译为ASCII码。-A simple implementation using Sockets communication: First run ASCIIServer.java run ASCIIClient.java. And the client will be sent to the service side 65-90, and Translations Service client for ASCII code.

ip函数,ip地址比较，checksum等函数-ip function, ip address comparison, function and so on checksum

java程序设计网络编程课后习题fibonacci序列编程！-java programming network programming Problem fibonacci sequence of after-school programming!

这是一个简单的socket编程的例子，它是基于TCP协议的，从中可以看出用TCP建立连接时客户端和服务器端的程序流程，可以用来测试本地环路。-This is a simple example of the programming socket, which is based on TCP, can be seen with the establishment of TCP connections client and server-side program flow can be used to test the local loop.

说明：  基于Skey协议的网络通信。MD5加密算法的运用。(Network communication based on S-key protocol. Application of MD5 encryption algorithm.)

说明：  用于机器人的开发控制和机器人运动学研究，并且实现一般网络通讯的开发(Development and Control of Robots)

说明：  学习synflood 写的例子！！！见谅(about tcp synflood attack learn example)

MD5加密，网上找很多都不合适，自己写一个。(MD5 encryption, the Internet to find a lot of inappropriate, write one yourself.)
