                BufferedInputStream b_IS=new BufferedInputStream(f_IS);
                DataInputStream d_IS=new DataInputStream(b_IS);
                while(d_IS.available()!=0){
                String line=b_R.readLine();
                System.out.println(line);
                }
                d_IS.close();
                b_IS.close();
                f_IS.close();
                /*while(line!=null){
                System.out.println(line);
                line=b_R.readLine();
                }*/
     
     
     
        }
     
    }

    I want to read the file but i don't know why it's not reading the first line. Can any of you suggest me, where to look exactly.... Thanks for reading the post.
