I want to create a program using Java to simulate the process of getting a Ticket for a Plane. For this I have four sections: First class with a capacity of $50$ and a price of $$700,$ Bussiness class with a cpacity of $70$ and price $$500,$ Tourist class $,$ with a capacity of $100$ and a price of $$350$ and Basic class with a capacity of $200$ and a price of $$235.$ I need to create$/$ populate the seats. Seats having$($Section$,$ row, seat number$).$ This has to be done using sets. I want to show the number of seats available.I also need to reserve the seats the client choose from the available seats, and reserve them. Storing their transaction in an arraylist. And using a HashMap to map the clients, with the seats they bought. Finally I need to show the users their final total. $($In the reservations I also want to allow clients to choose from different sections if they want to$)($Thanks in advance$)$
