+# AirLineReservationSystem
+A Java-based airline reservation system that uses Object-Oriented Programming. The system can manage customers, admins, flight booking and cancellation. 
+It also includes many other features implemented in Java using OOP concepts like inheritance, encapsulation, association, and composition.

+# Features
+The reservation system demonstrates the role of both the admin and the passenger. The admin sets up and manages the reservation system, while passengers use it to make reservations.
+## 1. Customer Registration
+In order to get started with the program, you need to register first. Make sure you remember your login information, as you will need it to sign in.
+Registration screen can be seen in the image below:

+## 2. Customer Login
+You can access all the features of the program by logging in with your credentials. After successful login, you can avail all the features offered by the program.

+### A. Book Flight
+This module helps customers book a flight. Customers must enter the flight number and the number of tickets for the flight in order to make a reservation. An example is shown in the image below:

+### B. Update Data
+This section allows users to modify their bio-data. Data includes name, email, phone number, address and age.
+If the user edits his data, logouts eventually and tries to log in with the old email, he won't be able to log in as his old email has been replaced.

+### C. Delete Account
+If a user decides to delete their account, they can do so and all the data related to the account will be deleted. However, any flights that were registered by the user before they deleted their account will still be in the records.

+### D. Random Flight Schedule
+This segment of the program shows the scheduled flights for this instance. The schedule may change as the program runs again.
+The schedule updates as users book or cancel registered flights. The number of available seats decreases on booking of flights and increases when a user cancels a registered flight.
