Question

Railway Online Booking System requires a Queue to manage Passenger Booking Data Collection. A

Booking queue should be an abstract data type for add and remove Booking Element. [The first element added to a queue has the preference to be removed (first-in-first-out, FIFO). ]

Apply abstraction Using an Interface. Introduce Composition or Inheritance in your class with Collection interface. Ensure Naming standards and access specifier are correctly applied. Booking Queue must have an Booking Object with data like name, from, to, trainNo.

Note : Use any type of Collection Interface you know. [We don't expect that you should only use
java.

Answer 1

The question entails creating a queue system for a Railway Online Booking System using an interface with composition or inheritance along with a collection interface like LinkedList, containing data such as passenger name, points of travel, and train number.

Step-by-step explanation:

Designing a Railway Online Booking System Queue

Implementing a queue for a Railway Online Booking System that follows the first-in-first-out (FIFO) principle requires the use of an interface to abstract the data type for adding and removing booking elements. Through composition or inheritance, one can integrate a collection interface with classes that allow manipulation of the booking data.

The Booking Queue will utilize a collection interface such as a LinkedList in Java to manage the queue of bookings. Each booking object will contain passenger details such as name, source station (from), destination station (to), and train number (trainNo).

Here is a conceptual example:

• 
  
• An interface IBookingQueue that defines methods for enqueuing and dequeuing booking objects.
• 
  
• A class Booking that encapsulates the booking details.
• 
  
• A class BookingQueue that implements IBookingQueue and uses a LinkedList to manage the queue.

Naming conventions and access modifiers will be applied to ensure clarity and encapsulation of the data.
