      String readStr=null;
      int writeStr=1;
      try
         {
             file=new BufferedReader(new FileReader(countFile));
            readStr=file.readLine();
            }catch(IOException e)
             {

    else

        writeStr=Integer.parseInt(readStr)+1;
       }try{
           PrintWriter pw;
            pw=new PrintWriter(new FileOutputStream(countFile));
            pw.println(writeStr);
            pw.close();
