1.控制臺輸入英文文本，讀取文本內容。

String content = "";
String con = null;

while(content!=null){    
content = bufferedReader.readLine();    
if(content == null){        
            break;
            }
    
 
if(content.equals("")){    
            continue;
        }
        count += getWord(content, map);    

        System.out.println("該篇文章總字數為："+count+"個");

檢測單詞中是否包含特殊字符，若有，則用""空串替代。

public static String checkIsHaveSpecial(String word) {
        String[] special= {",","(",")","-","*","\"","?",".","—","=","+","","!","/","1","2","3"
                ,
 
"4","5","6","7","8","9","0",":","$","@"," ","（","）"};    //特殊字符集
        for(int i = 0;i<special.length;i++) {
            if(word.contains(special[i])) {
                word = word.replace(special[i],"");
            }
        }
        return word;

2.控制臺輸入英文文本，統計單詞和出現次數。調用getWord方法獲取字母並添加到map中，並返回每一行的單詞數，並相加。

public static void main(String[] args) throws Exception {
        
        Scanner sc = new Scanner(System.in);

        String content = "";
        
        String con = null;
        con = sc.nextLine();
        Map map = new TreeMap<String,Integer>();
        int count = 0;    
        count = getWord(con, map);
        
        System.out.println("該篇文章總字數為："+count+"個");
        sortMap(map);
    }

3.選擇文件，輸入文件路徑，讀取文件。

    public static void main(String[] args) throws Exception {
    
      String f;
      System.out.println("請輸入文件路徑：");
      Scanner sc = new Scanner(System.in);
      f = sc.nextLine();
      File file = new File(f);

4.從控制臺輸入英文單篇作品。

    public static void main(String[] args) throws Exception {
        File file = new File("C:/book.txt");
        BufferedReader bufferedReader = new BufferedReader(new FileReader(file),1024*1024*1);
        
        String content = "";
        
        Map map = new TreeMap<String,Integer>();
        
        int count = 0;    
        
        while(content!=null){    
            content = bufferedReader.readLine();    
            if(content == null){    
                break;
            }
            if(content.equals("")){
                continue;
            }
            
            count += getWord(content, map);    
        }
        
        System.out.println("該篇文章總字數為："+count+"個");
        sortMap(map);
    }

程序做得少，框架來的很慢，在執行中有多次錯誤，很多小問題，花費了很多時間才修正，例如在裏面查找文件夾目錄裏的小說時，沒有註意txt的後綴問題，後來一點點排出才發現。

1.測試功能的實現
