1. 代码来源：
博客园http://www.cnblogs.com/duasonir/p/5297338.html
2. Platform：Eclipse
Language：Java
3. Bug：暂时还没有bug
4. Function improvement：所找的代码的各个扩展已经很全面，主函数用string字符串接受用户输入，并分解成参数数组和文件地址。编写BaseCount()函数实现对文件的读操作，逐行统计统计字符数，并记录行数，同时使用StringBuffer类记录文件中所有的信息。最后一起统计词数，避免在逐行计词时，把标点计为一词。编写Response()函数根据用户输入的参数输出信息，这里程序不管用户输入的参数是什么，都在读取文件的时候把所有信息都记录下来并保存，用户输入的参数里有什么输出什么。
5. Implementation：可实现
6.代码如下：
