   今天的上機以自學為主,以為實在對檔案處理一點以不會。學會了對檔案的讀入和輸出等,完整代碼還不完成,以下為一部分,還不夠完整成熟。

設計思路:

1 檔案讀入

2 單詞之間是以空格隔開的,以此來截取單詞

3 進行相同單詞的比較統計

4輸出單詞的個數

原始碼(部分):

import java.io.BufferedReader;import java.io.FileNotFoundException;import java.io.FileReader;import java.io.IOException;import java.util.HashMap;import java.util.Map;import java.util.Set; public classTest {     public static void main(String[] args) {         BufferedReaderbr = null;         try {              Map<String,Integer>map = newHashMap<String,Integer>();              br = new BufferedReader(new FileReader("d:/mywords.txt"));              Stringline;              while(null != (line = br.readLine())){                   System.out.println(line);                   String[]ss = line.split("\\s+");                   for(String s : ss){                       if(map.containsKey(s)){                            map.put(s, map.get(s)+1);                       }else{                            map.put(s, 1);                       }                   }              }              Set<String>keys = map.keySet();              for(String key : keys){                   System.out.println(key + "有:" + map.get(key) + "個.");              }         }catch(FileNotFoundException e) {              e.printStackTrace();         }catch(IOException e) {              e.printStackTrace();         }finally {              if(null != br){                   try {                       br.close();                   }catch(IOException e) {                       e.printStackTrace();                   }              }         }     }}
