说明：  birch算法是聚类算法的一种，克服了k-means算法的缺点，这里提供了详细的讲解ppt和代码(The birch algorithm is a kind of clustering algorithm, which overcomes the shortcomings of the k-means algorithm. Here is a detailed explanation of ppt and code.)

JSI (Java Spatial Index) RTree Library 是一个RTree算法Java实现的开源库，理论来源是Guttman1984年的一篇论文"R-trees: A Dynamic Index Structure for Spatial Searching" by Antonin Guttman",论文可见(PDF on CiteSeerX). 这个开源项目的代码遵循 GNU Lesser General Public License 最新的代码可以在http://github.com/aled/jsi上找到 同时例子在https://github.com/aled/jsi-examples(The JSI (Java Spatial Index) RTree Library open source Java implementation library of a RTree algorithm theoretical source of the Guttman1984 paper R-trees: A the Dynamic the Index Structure for Spatial, Searching by Antonin Guttman, papers can be seen (PDF onCiteSeerX).

能实现简单的加，减，乘，除四则运算，完整源码，能运行(for simple calculate)

无作用,无需下载,不用预览,只是开通功能(No effect, no downloading, no preview, only open function)

直接运行compile.bat和run.bat即可 使用了3种分词方法： 1.正向最大匹配(ForwardMatch.java) 2.逆向最大匹配(ForwardMatch.java) 3.最大频率匹配(FrequencyMatch.java)(默认) 取频率最高的词，然后两端递归，构建二杈树存储句子中的词语，显示的时候使用中序遍历二杈树 由于极有可能单个字的使用频率比整个词还高，筛选的时候进行了处理 若单个字不处于当前句子开头，先忽略， 若单个的字处在开头，临时mostFrequency仍为0，且单词长度为1，则加入到二杈树中(Can be run directly compile.bat and run.bat used three kinds of segmentation methods: 1. Being the biggest match (ForwardMatch.java) 2. Reverse maximum matching (ForwardMatch.java) 3. Maximum frequency matching (FrequencyMatch.java) ( default) to take the highest frequency words, and then both ends of the recursive construct two Cha tree storage sentence terms, when used in the sequence shows two Cha tree traversal is very likely because the use of a single word frequency is higher than the whole word, screening If the time were dealing with a single word is not in the beginning of the current sentence, first ignored, if a single word at the beginning of the temporary mostFrequency still 0, and the word length of 1, to 2 Cha tree)

分词程序，正向最大匹配法，JAVA语言。核心思想是从句子最左端开始，单字节扫描匹配，直至句末(Segmentation procedure, forward maximum matching, JAVA language. Core idea is to start from the leftmost sentence, single-byte scan match until end of the sentence)

一些常见的JAVA面视题,希望能对各位有所帮助.(JAVA face some common as the title, I hope you can help.)

源代码转换的一个小小的实现,写得比较一般,但是功能齐全(Source code into a small implementation written in general, but fully functional)
