Railways.

java Explanation

This Java class serves as the main interface for a railway reservation system,
enabling users to book tickets, view passenger details, check available tickets,
and cancel reservations.

Main Structure:
1. Main Method:
- Continuously runs a loop allowing the user to select different options:
- 1. Booking
- 2. Passengers
- 3. Available Tickets
- 4. Cancel
- 5. Exit
- Based on the user's choice, it calls the appropriate method.

2. Methods:
- bookTicket(): Handles booking logic for a passenger.
- cancelTicket(int id): Cancels the ticket for a passenger based on the
provided ID.
- suggestBerth(Passengers p): Suggests available berths if the preferred one is
not available.
- racBookTicket(Passengers p): Books a ticket for a passenger on RAC
(Reservation Against Cancellation) or suggests available options.

Detailed Method Breakdown:

1. main Method:
- A while (true) loop runs indefinitely, providing a menu for the user.
- The switch statement handles the user's input:
- case 1: Calls bookTicket() for ticket booking.
- case 2: Creates a TicketBooker object and calls printPassengers() to
display passenger details.
- case 3: Creates a TicketBooker object and calls printAvailTickets() to
display available tickets.
- case 4: Asks for a passenger ID and calls cancelTicket(id) to cancel the
ticket.
- case 5: Exits the program.
- default: Handles invalid inputs.

2. bookTicket():
- Prompts the user to enter passenger details (name, age, berth preference).
- Creates a Passengers object with the entered details.
- Checks ticket availability and assigns a berth based on the preference. If
the preferred berth is not available, it calls suggestBerth(p).
- If no tickets are available, it adds the passenger to RAC or waiting list.

3. cancelTicket(int id):
- Checks if a passenger with the given ID exists.
- If yes, it creates a TicketBooker object and calls cancelTicket(id).
- If no, it prints "No Such user found".

4. suggestBerth(Passengers p):
- Lists available berths and prompts the user to choose one.
- Books a ticket based on the user's choice.

5. racBookTicket(Passengers p):
- Checks if the preferred berth is available. If yes, it books the ticket.
- If the preferred berth is not available, it assigns the first available berth
or adds the passenger to RAC or waiting list based on availability.

Usage Summary:
- The Railways class is the entry point for interacting with the railway
reservation system.
- It utilizes the TicketBooker class to handle core booking and cancellation logic.
- The Passengers class is used to represent individual passengers in the system.

This setup allows for a modular approach where the Railways class handles user
interactions, and the TicketBooker class manages the business logic.
