bufferedreader when reading after eof issue ioexception

instead suggest use scanner read files code like...(in serverside)

scanner scnfile=new scanner(new file("display_client.txt")); //give absolute path if necessary  while(scnfile.hasnext()){  system.out.println(scnfile.nextline());  }  scnfile.close();
