For loop not working & way to include an external file

Question

Hi everyone, i am new to java and am having some problems with my program.
I have a for loop but it doesnt work it completely gets ignored and i have
no idea why it does that.
IS there a way that i add another option in the menu to open an external file
which would be similar to this but it would be for cabinBooking. If so how do
i do that. if opening an external file is impossible then could you please show me an example of how to extend the booking class.
Any help would be appreciated.
Thank you very much

Answer 1

in order to extend the Booking class, you can create anew class like this..
public class CabinBooking extends Booking
   public CabinBooking( /*String bId, String bName,int bNum .. more args or fewer, or none.. */)
    // add new methods or override ones from Booking
}
