Help Please Urgent

Expand Post »
hello everyone,

im trying to make a theatre program and im at a dead end so im hoping for some help please.
if someone can help see my problem clearer or post some sample code it will be much apperciated.

the problem is i need to create a Seat class in the theatre program but im unsure of how it will work or how i can do it.

i have been asked to create a seating system which will hold around 400 seats. but the seats are split into different sections. e.g upper circle will hold 100 seats etc. it needs to be oop based.

the seats are split into rows and a row of seats my have different pricing e.g. row 1 and 2 may be priced at £10 per seat.

also i have to make sure that the seats are not doubled booked but i really am struggling with how to do all the above.

Last but not least lol can java applets use mvc as i have only done mvc on jframes so im not totaly sure??

all feedback and help is much appericated

thanks

Re: Help Please Urgent

Depending on the attributes that different seats may have you can choose to either implement them as different type of seats or keep a 'type' attribute in the Seat class that gives their type, if they do not differ much.

>also i have to make sure that the seats are not doubled booked
To avoid double booking you can keep a flag isBooked in the seat class that tells whether the seat is booked or not.

I assume you are acqauinted with OOPS concepts, if not you can read about that on the net.

Re: Help Please Urgent

hey verruckt24 well im not even sure what attributes to have lol i mean i know i would have price, num of seats in row , number of rows and isbooked as you have suggested. can you think of anymore?? also im not sure how isbooked will work do i have to do some check in the class eg query the data in the database?? if you know what i mean.

ummm the thing is most of the seats areas eg upper circle the only difference is the price for each row ect otherwise there identical.
what do you mean by 'type' attribute??

yes i have done some oop before not much though lol thanks for your quick reply

In the constructer of your seat class, have a boolean for the booked status.

then have a method that simply returns the true or false value of the seat

Re: Help Please Urgent

What I meant was, if your seats do differ a lot in attributes other than price you would want to have a different class for each of them, say, UpperCircleSeat, DressCircleSeat, LowerCircleSeat etc. where all of these could be deriving from one common Seat base class. But as you mention that it's not the case, you can just have one Seat class with attributes such as Price, Type (UpperCircle,LowerCircle etc), isBooked, SeatNo which could be combination of row number and seat number within that row say, A4, F5 etc. These are all the attributes that come to mind.

Re: Help Please Urgent

As I mentioned in first post you need to model your program close to the real world scenario. In our world a Theatre is made up of a collection of seats, so what you can do is, make a Seat class as suggested in the previous posts and then you could have an array of the Seat objects.

Create a Seat class and then create an array of Seat objects the same way you would create one for String or int etc.,
java Syntax (Toggle Plain Text)
  1. Seat [] seats = new Seats [10];
