说明：  ipdatabase 二叉树快速搜索IP地址数据库 数据 数据源采用2015年广告协会制定的IP地址标准数据库，中国互联网广告行业统一采用的标准IP库。 原理 利用二叉树实现IP查询，首先将10进制IPV4地址转化为二进制构建二叉树，利用二叉树搜索进行搜索，查询时间复杂度log2n，比传统IP库n的查询速度高出一个量级。(Ipdatabase Binary Tree Fast Search IP Address Database data The data source is the standard IP address database formulated by the Advertising Association in 2015, and the standard IP database adopted by the Internet advertising industry in China. principle The binary tree is used to realize IP query. Firstly, the 10-bit IPV4 address is converted into binary to construct a binary tree, and the binary tree search is used to search. The query time complexity log2n is one order of magnitude higher than that of traditional IP library n.)

人工蜂群代码,用于算法的基础学习，仅供参考。 也可以用来进行java代码的学习(Artificial bee colony code, for the basic learning algorithm. It can also be used to learn java codes)

miniCAD-java GUI实现的小型CAD软件，界面其实模仿了windows画图的风格，实现了画线、画圆、画矩形、画文字载入图片，并能改变图形的颜色和大小。(In this project, you should use Java GUI to implement a simple drawing board. To get full marks, you should implement to: 1.draw line, circle, rectangle, text 2.change the color of a target 3.change the position of a targets 4.change the size of a targets 5.save images as files and load a image file All processes of changes should be visible.)
