Airline Reservation System Using Java With Source Code

Abstract:

The code is an example of an airline reservation system implemented in Java language. The program uses an array of boolean values to represent the seats on a plane, where a value of true indicates a seat is reserved and a value of false indicates a seat is available.

Introduction:

Airline reservation systems(ARS)are critical for managing and booking flights. These systems are used by airlines to handle passenger bookings, manage flight schedules, and track ticket sales. In this article, we will explore a simple Java program that simulates an airline reservation system.

Explanation:

The Code uses an array of boolean values to represent the seats on the plane. A value of true in the array indicates that a seat is reserved, and a value of false indicates that a seat is available. The program has a main method part that serves as the entry point and contains a while loop that displays a menu to the user with three options:

Reserve a seat
View all seats
Exit

When the user selects option 1, the program calls the reserveSeat method. This method prompts the user to enter a seat number and then checks if the seat is available (i.e. the corresponding value in the seats array is false). If the seat is available, the program reserves the seat by setting the corresponding value in the seats array to true, and displays a message to the customers. If the seat is not available, the program displays a message to the user indicating that the seat is already reserved.

If the user selects option 2, the program calls the viewSeats method. This method loops through the seats array and displays the status of each seat (i.e., whether it is available or reserved) to the user.

Finally, if the user selects option 3, the program exits the while loop, and the program ends.

While this example is a simple and Easy to use, it demonstrates how an airline reservation system can be implemented using Java. However, it’s important to note that this is not a complete solution, it doesn’t cover all the features that a complete Airline Reservation System would have, such as authentication, booking history, flight schedule, payment gateway integration, etc. It also doesn’t include error handling, data validation and other important features that would be included in a production ready system. But it is a good starting point for those who are interested in understanding how the basic functionality of an airline reservation system can be implemented in Java.

        int seatNum = input.nextInt();
        if (seats[seatNum - 1] == false) {
            seats[seatNum - 1] = true;
            System.out.println("Seat reserved. Thank you.");
        } else {
            System.out.println("Sorry, this seat is already reserved.");
        }
    }
 
    private static void viewSeats() {
        for (int i = 0; i < seats.length; i++) {
            System.out.print("Seat " + (i + 1) + ": ");
            if (seats[i] == true) {
                System.out.println("Reserved");
            } else {
                System.out.println("Available");
            }
        }
    }
}

In conclusion, airline reservation systems are a crucial component of the airline industry, and their proper implementation can greatly improve the efficiency and profitability of an airline. This simple Java program demonstrates one possible approach to implementing an airline reservation system, but it’s important to keep in mind that there are many other ways to approach this problem and that a production-ready system would require a lot more features and considerations.
