北大青鸟的java学习文档，一共有4份，这是第四份，希望对大家有帮助。-Beida Jade Bird to learn the java files, a total of 4, this is the fourth, in the hope that everyone has to help.

Samples are organized by chapter, and then by "application" or example name. You should open a project in Visual Studio .NET through the .sln (solution) file. Note that Visual Studio .NET automatically creates various temporary and debugging files in the obj and bin sub-directory for each project. The actual uncompiled code is only the .vb files that are contained in the root project directory.

这是一个瑞杰的软件，主要用于上网的应用程序。-This is a瑞杰software, mainly for Internet applications.

一个模拟泊松随机过程的小程序。可以计算系统平均等待时间，和平均对列长度。系统参数如 到来速率及离开速率均可在头文件里修改。另外通过修改头文件factorK可以将到来序列的概率分布改为Erlang分布。-a simulated Poisson random process of small programs. System can calculate the average waiting time, and the average length of the list. The system parameters such as the rate of arrival and departure rates can be found in the first document changes. Through the first revised document will come factorK sequence probability distribution instead Erlang distribution.

用API函数编写一个键盘处理程序，要求在窗口中绘制一个矩形，大小与颜色自己确定，当按光标键时，矩形能够随之移动，若按字符键时能够将按键的字符写在矩形中，写满自动清空。-used to prepare an API function keyboard handling procedures, requirements in the window drawing a rectangle, Size and color set ourselves that if the cursor keys, will be moved to rectangular, According to Key characters will be able to switch characters written on the rectangular, written all over automatically emptied.
