我用了三个类：一个菜单Menu类，一个中间算法处理WordFrequency,一个结果显示DisplayFace类.
DisplayFace中我用了一个jfreechart来做界面显示
map作为三个类的中间传递的参数
实现了map<key,value>的按照key和value排序
做完这个程序我感觉自己的程序一步步在简化,这个过程我感觉自己挺笨拙的，一开始想到的都是最笨的办法进行文件学些、排序，没想过map，以前也从没用过map,后来在写程序的过程中，自己总是在想办法，然后百度搜怎么解决这个问题，然后自己看别人怎么实现的，看懂了，然后拿来用在自己的程序当中，一开始界面我不知道做成什么样的，厚爱搜到草莓在努力的博客园里面的界面，然后我的菜单界面也实现成和他一样。我很享受写程序这个过程，不仅仅是写程序，关键是在想办法，然后解决问题，这个过程中成就感油然而生，导致每天走在路上，吃饭都会想这个问题怎么解决，上课被老师拿粉笔打，甚至逃课。。。。。。。。。。。。。。
希望大家看了我的程序都说说我程序的不足吧，或者哪些地方你们有更好的解决办法，都可以评论，我希望我们都能互相学习，共同进步。。。。。。。。。。
