        } catch (FileNotFoundException e) {
     
            e.printStackTrace();
        }
        String line="";
        String everyLine="";

        while (true)
        {
     
            try {
     
                if (!((line=br.readLine())!=null)) break;
            } catch (IOException e) {
     
                e.printStackTrace();
            }
            everyLine=line;
            System.out.println(everyLine);
            allString.add(everyLine);
        }
        System.out.println("csv表格所有行数:"+allString.size());

    }
}
