Airline Reservation System

How does the Java code for the airline reservation system work?

The Java code for the airline reservation system is provided. What are the key functionalities and processes outlined in the code?

Overview of the Java Code

The Java code for the airline reservation system is designed to assign seats on each flight of the airline's only plane and manage baggage weight for customers. The code uses a one-dimensional array to represent the seating chart of the plane and tracks seat reservations and total income. Here's a breakdown of how the code works:

• The code initializes a Boolean array to represent the available seats on the plane.
• It prompts the user to enter a seat number and checks the validity of the input.
• If the seat is available, the code prompts the user to enter the weight of their bag and calculates extra weight fees if necessary.
• A confirmation message is displayed if the reservation is successful, including seat number, extra weight fees, and total fees.
• If the seat is already reserved or the baggage weight exceeds the limit, a rejection message is displayed.
• The reservation process continues until the user enters -1 to end the program.
• At the end of the program, a summary of the number of reserved seats and total income is displayed to the user.

Details of the Java Code

The Java code for the airline reservation system is structured to ensure a smooth reservation process for customers. Here are the detailed steps involved:

1. Seat Reservation Process:

The code starts by initializing the seating chart array with all seats set to false, indicating they are available. It then prompts the user to enter a seat number within the valid range (1-10 seats).

If the seat is available, the code proceeds to request the weight of the customer's baggage. It checks if the weight is within the allowed limit (up to 20 kg) and calculates any extra weight fees if applicable.

If the reservation is successful, the seat is marked as reserved in the array, incrementing the total number of reserved seats and adding the appropriate fees to the total income.

2. Handling Invalid Inputs:

If the seat number entered is invalid (not within the range or already reserved), the code displays an error message and prompts the user to input a valid seat number.

If the baggage weight exceeds the limit, the code alerts the customer with a message and requests a new input for the baggage weight.

3. Ending the Program and Summary Display:

The reservation process continues until the user chooses to end the program by entering -1. At this point, the code displays a summary of the total number of reserved seats and the accumulated income from the reservations.

Overall, the Java code provides a user-friendly and efficient way to manage seat reservations and baggage weight for the airline.
