Question

Objective: To implement the programming languages features discussed in class and to develop a program that uses Graphical User Interfaces (GUI) that provides a friendly environment for users.

Project Assignment

Design and implement a Hotel Reservation System. The hotel has two types of rooms. One is regular room that has two beds. Another is deluxe room that has two beds and a safe. The regular room price is $120 per night. The deluxe room is $130 per night. A safe cost additional $20 per night (only for deluxe room). The hotel has 10 rooms. This system should allow an agent to input a customer name, select a room type, using the safe box or not as well as arrival and departure dates. It should also provide the capability to calculate the total charge and display it on the screen. The hotel reservation system must satisfy the following requirements:

1. An interface should be developed to allow an agent to input required information.

2. The system must test for required fields

3. The system must show the use of arrays

4. A person reserves a room via reserve method. This method returns an integer indicating the room number. If a customer tried to reserve a room, but the rooms are sold out, and error message should be displayed.

5. If a customer reserved a room the person’s name, arrive time, departure date, room number,and total charge should be displayed.

6. Must use and run in Java NetBeans 8.0.2 or higher (Please specify when you submit your code)

7. Turn in the all project folder using the blackboard digital drop box

8. Code must follow proper programming standards (comments, indentation, proper variables names, etc.)

9. No partial credit will be given if the program does not run.

10. Please submit your project folder in a zip file

11. No late assignment will be accepted
