. etc

的帮助你，我希望：

public static void readSplitWrite(String pathToFile){ 
    //To recognize how are your sentences : between 1 and 25 digit, then some spaces, and then what you want 
    Pattern patt = Pattern.compile("([0-9]{1,25})\\s*(.*)"); 
    try { 
     //Read over all the lines of your file 
     for(String line : Files.readAllLines(Paths.get(pathToFile),Charset.forName("UTF-8"))){ 
      //Catch the different parts of the string (group(0) is the hole sentence, group(1) is inside first(), group(2) is inside second() 
      Matcher m = patt.matcher(line); 
      if(m.find()){  
       //Open a file, in UTF-8 encoding (to be able to read Arabic character, as name the ID 
       Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(m.group(1)+".txt"), "UTF-8")); 
       try { 
        //write the content into 
        out.write(m.group(2)); 
       }catch (Exception e) { 
        e.printStackTrace(); 
       } finally { 
        out.close(); 
       } 
      } 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} 

public static void main(String[] args) { 
    //Just the name if the file is in the folder, if not write absolute path 
    String pathToFile = "Text.txt"; 
    readSplitWrite(pathToFile); 
} 

此代码将阅读您的文件，然后对每行创建一个new File，与姓名的数量，作为内容的句子 如果有任何问题，告诉我在评论
