文件读取器程序未打印单词的全部字母

Question

import java.util.TreeMap; 
import java.io.*; 
import java.util.Map; 

public class ReadFile { 
    public static TreeMap<String, Integer> generateFrequencyList() 
      throws IOException { 
     TreeMap<String, Integer> wordsFrequencyMap = new TreeMap<String, Integer>(); 
     String file = "file1.txt"; 
     BufferedReader br = new BufferedReader(new FileReader(file)); 
     String line; 
     while ((line = br.readLine()) != null) { 
      String[] tokens = line.split("\\s+"); 
      for (String token : tokens) { 
       token = removePunctuation(token); 
       if (!wordsFrequencyMap.containsKey(token.toLowerCase())) { 
        wordsFrequencyMap.put(token.toLowerCase(), 1); 
       } else { 
        int count = wordsFrequencyMap.get(token.toLowerCase()); 
        wordsFrequencyMap.put(token.toLowerCase(), count + 1); 
       } 
      } 
     } 
     return wordsFrequencyMap; 
    } 

    private static String removePunctuation(String token) { 
     token = token.replaceAll(",", "").replaceAll("\\.", "").replaceAll(";", "").replaceAll("!", ""); 
     return token; 
    } 

    public static void main(String[] args) { 
     try { 
      TreeMap<String, Integer> freqMap = generateFrequencyList(); 
      for (final Map.Entry<String, Integer> entry : freqMap.entrySet()) { 
       final String key = entry.getKey(); 
       final Integer value = entry.getValue(); 
       float total = 0; 
       for (final Integer wordCount : freqMap.values()) { 
        total += wordCount; 
       } 
       final float percentage = (value/total) * 100; 
       System.out.println(key + " = " + value + " => " + percentage); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

我需要该程序来读取.txt文件并返回单词列表，频率和百分比。我使用的.txt文件比打印出的文字多。这似乎只是印出T - Z的单词。我不知道如何解决它给我所有的话。任何人都有一些想法，为什么它不给我整个单词列表？

Answer 1

对我来说工作正常..也许你的测试文件和例子可能会有所帮助.. 只是一个提示..而它可能会想要在for循环之外计算“total”。 :)

仅供参考我没加br.close（）因为我的编辑抱怨说，BufferReader没有被关闭。但是这不影响输出。

 } 
    } 
    br.close(); 
    return wordsFrequencyMap;
