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.)

JAVA中解决编程过程中出现乱码的情况，这是个很好的方法(JAVA programming process to address the situation of garbled, this is a good way)

设计模式一（单子、工厂、策略模式）练习 1． 假设现在要设计一个贩卖各类书籍的电子商务网站的购物车系统。对所有的教材类图书 实行每本一元的折扣；对连环画类图书提供每本7%的促销折扣；而对非教材类的计算机图书有3%的折扣；对其余书没有折扣。使用策略模式、工厂模式、单子模式进行设计(Design Mode 1 (List, Factory, Strategy Mode) Exercise 1. Suppose we are going to design a shopping cart system for e-commerce websites that sell all kinds of books. All textbook books are discounted at one yuan per book; comic books are discounted at 7% per book; computer books are discounted at 3% for non-textbook books; and other books are discounted at no rate. Design using strategy mode, factory mode and single mode)

同学写用Java写的 模仿千千静听音乐播放器源代码，界面超漂亮，程序代码简洁，不过程序比较综合，估计没有基础的JAVA朋友不好看懂，想研究一下的可下载试试。编译时需要在Eclipse下打开，并导入源码包目录下的必要库文件才行。(Students to write in Java to write the music player to imitate TTPlayer source code, the interface super-nice, clean code, but more comprehensive program, it is estimated based on JAVA friends did not understand well, to look at the downloadable try. Compile time to open in Eclipse, and import the necessary source package library directory the job.)
