//lat=3434&lon=yy38&rd=1.0&| in that format o/p is displaying

public class ReadText {
    public static void main(String[] args) throws Exception {
        FileInputStream f= new FileInputStream("D:/workplace/sample/bookstore.txt");
        BufferedReader br = new BufferedReader(new InputStreamReader(f));
        String strline;
        StringBuffer sb = new StringBuffer();
        while ((strline = br.readLine()) != null)
        {
            String[] arraylist=StringUtils.split(strline, ",");
            if(arraylist.length == 2){
                sb.append("lat=").append(StringUtils.trim(arraylist[0])).append("&lon=").append(StringUtils.trim(arraylist[1])).append("&rt=1.0&|");

            } else {
                System.out.println("Error: "+strline);
            }
        }
        System.out.println("Data: "+sb.toString());
    }
}
