        LinkedList arr = new LinkedList();
        BufferedReader br = null;
        try{
            br = new BufferedReader(
                    new FileReader(source));
            String info = null;
            while((info = br.readLine()) != null){
                arr.add(info);
            }
        }catch(FileNotFoundException e){
            System.err.println("文件未找到");
        }catch(IOException e){
            System.err.println("文件读取出错");
        }catch(Exception e){
            System.err.println(e.getMessage());
        }finally{
            try{
                br.close();
            }catch(IOException e){
                System.err.println(e.getMessage());
            }
        }
        String[] results = new String[arr.size()];
        arr.toArray(results);
        return results;
//        return stringHashMap;
    }

//    public static void main(String[] args) {
//        ReadTxt readTxt = new ReadTxt();
//        Map map = readTxt.openTextFile("D:\aaa.*.txt");
//        for (String s : map.keySet()) {
//            System.out.println(s+":"+map.get(s));
//        }
