第一次作业

在这次作业中，我用了java实现了词频排序程序，

输入规格如下：

Require：
1、搜索路径由命令行参数输入。应为全路径，应为文件夹路径而非具体文件路径，否则程序报错。

2、搜索单词由控制台输入。

Effect：
1、输出格式如PPT，上下文输出时，忽略标点符号。

2、任何输入错误（包括命令行、控制台、文件中的与PPt和ReadMe不符的地方），输出：Input error，程序结束。

3、合法的txt文件内容要求如PPT。

输入样例：
#（命令行参数：D:\test）（我把通用测试用例放在了D盘下）
#（控制台输入如下：）
A
I
key
aaaaaaaaa

输出样例：
Total Files-Number : 81 Total Words-Number : 5110
