For loop not working & way to include an external file
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
