使用Java 编制的小游戏，实现了客户端与服务器端的简单连接-Prepared using the Java game to achieve the client and server-side of the simple connection

一个服务器客户模式的小型考试系统,有兴趣的可以DOWN回去后改进成实用的系统(华南农业大学信息学院计算机系).-a client server model of the small test system, interested DOWN can go back into improving the practical system (South China Agricultural University, Department of Computer Information Institute).

JAVA编写的一个简单计算年龄的计算器,首先输入DOG YEARS的数值,HUMAN YEARS得到的结果相应的乘以10 得出!很明朗! -JAVA prepared by a simple calculation of the age of calculators, the first DOG YEARS numerical input, HUMAN YEARS corresponding results obtained by multiplying 10! Very uncertain!

客户通过Socket(InetAddress,port)建立与服务器的连接。服务器与客户都通过构造BufferedReader,PrintWriter来建立输入输出流，然后双方通过该输入输出流来相互传递信息，一旦收到客户方的连接请求，服务器accept()方法返回一个新建的Socket对象。客户端然后向服务器发送消息，比如注册，登录，查找好友等，服务器收到来自客户的请求后，针对不同的消息处理请求, 虽然UDP不可靠但是对于icq可靠性并不太重要，而且UDP快速，所以客户间发送信息通过UDP。用户登录时通过类DatagramPacket和DatagramSocket创建UDP包括其本地接受端口以及发送端口，默认端口为5000和5001，通过取得的好友的IP地址来向好友发送消息（send(DatagramPacket)和接受消息(receive(DatagramPacket))。当用户通过UDP收到消息后，可以通过DatagramPacket的方法InetAddress getAddress()得到对方的ip地址，通过对好友列表比较以判断是谁并提示用户收到某某的消息，然后用户选择该用户查看消息，如果好友列表没有该人就显示收到陌生人的消息。用户可以按陌生人按钮查看消息。 -err

使用发射来处理JDBC的一个示例，可以作为初学者学习JDBC、jsp以及反射的一个例子-Launched to deal with the use of a JDBC example, can serve as a beginner to learn JDBC, jsp, as well as an example of reflection

A windows BMP file is a common image format that Java does not handle. While BMP images are used only on windows machines, they are reasonably common. Reading these shows how to read complex structures in Java and how to alter they byte order from the big endian order used by Java to the little endian order used by the windows and the intel processor.
