class RailwayTicket{

   String name;

   String coach;

   int amt;

   int totalamt;

   public void accept()throws IOException{

       InputStreamReader in = new InputStreamReader(System.in);

       BufferedReader br = new BufferedReader(in);

       System.out.print("Name: ");

       name = br.readLine();

       System.out.print("Coach: ");
