like this:

   File fp=new File(fname);
   int flen=(int)fp.length();
   buffer=new byte[flen];
    try{
      BufferedInputStream din=new BufferedInputStream (new
FileInputStream(fp));
     din.read(buffer,0,flen);
      din.close();
    }
    catch(IOException e){
      System.out.println("e);
    }
