解析文本中单词出现的次数小程序（JAVA）

在网上找了个题目练习了下，统计某个文本中单词出现的次数，也是用了状态机实现。

word类:记录单词及其次数

View Code

 1 package com.app;
 2 
 3 public class word {
 4     private String wordvalue;
 5     private double wordnum;
 6     
 7     public String getWordvalue() {
 8         return wordvalue;
 9     }
10     public void setWordvalue(String wordvalue) {
11         this.wordvalue = wordvalue;
12     }
13     public double getWordnum() {
14         return wordnum;
15     }
16     public void setWordnum(double wordnum) {
17         this.wordnum = wordnum;
18     }
19     
20 }
