In this project, you are required to write a project for a hotel management system: Phase $2$ will be as follows:

Write a java program that keeps displaying the main menu containing the following options:

A$.$ Show All Rooms

B$.$ Show Available rooms $($isOccupied $=$ false$)$

C$.$ Change room details

D$.$ Search by room type

E$.$ Search by capacity

F$.$ Sort and display rooms by pricePerNight ascending using your own sort method.

G$.$ Reserve a specific Room, set isOccupied$=$true, and input the customer first and last name in an array.

H$.$ Read room details from a file, update rooms based on the file. The format of each line in the file

should be as follows: roomNo RoomType isOccupied Capacity pricePerNight. For example:

$201$ Standard false $9250$

I. Save rooms data to file $($No need to store floor number as it can be extracted from room number$).$ The

format of each line in the file should be similar to the format of the reading file.

J$.$ Quit

$1)$ Class name: Room.java.

a$)$ A room has the following details

$(1)$ Integer Room number

$(2)$ Integer Floor number $($from $1$ to $5)$

$(3)$ String Room Type $($Standard$,$ Family, Suite$)$

$(4)$ Boolean isOccupied

$(5)$ Integer capacity

$(6)$ Double pricePerNight

$(7)$ Rooms on the first $20$ rooms $(1$ to $20)$ are standard, rooms: $21$ to $40$ are Family, and rooms: $41$ to $50$ are

Suite. All rooms have isOccupied $=$ false, and capacity $=2.$ The price per Night should be a random

integer between $0$ and $200($stored as a double$).$ Room numbers are numbered from $101$ to $110$ with

floor number$=1,201$ to $210$ with floor number $=2,301$ to $310$ with floor number $=3,401$ to $410$ with

floor number $=4,$ and $501$ to $510$ with floor number$=5.$

$(8)$ Array of Customer name staying in the room $($array size is $2$: the first element is the first name and the

second element is the last name$).$

$(9)$ Customer name is present only if isOccupied $=$true for a specific room.

b$)$ Write appropriate setters and getters for the room class, and toString method.

c$)$ Write appropriate methods to validate correct room numbers, room types, and capacities $($assume valid capacity

is from $1$ to $10).$

$2)$ Class name: RoomManagement.java: Room Management System which includes a one dimesional array of rooms of

the Room Class $($array size $=50).$ The Room management system allows the behavior of the menu described above.

The Room management system allows the following behavior:

a$)$ Show All Rooms

b$)$ Show Available rooms $($isOccupied $=$ false$)$

$2$

c$)$ Change room details: to allow to change the following room details at the same time: room type, isOccupied,

capacity, pricePernight. The user must first enter the room number; after that, the room details are entered

from the keyboard.

d$)$ Search by room type

e$)$ Search by capacity

f$)$ Sort and display rooms by pricePerNight ascending. Do not use any java ready methods for sorting. You must

write your own sort method.

g$)$ Reserve a specific Room, set isOccupied$=$true, and input from keyboard the customer name to stay in the

room. For each customer name, use a String array of size $2.$ The first element of the array is the first name of

the customer, while the second element of the array is the last name of the customer.

h$)$ Read room details from a file, update rooms based on the file. The format of each line in the file should be as

follows: roomNo RoomType isOccupied Capacity pricePerNight. For example:

$201$ Standard false $9250$

i$)$ Save rooms data to file $($No need to store floor number as it can be extracted from room number$).$ The format

of each line in the file should be similar to the format of the reading file.

$3)$ Create a Driver class that allow shows the menu above and creates a RoomManagement object and when selecting

Room Management System allows the above behavior. All keyboard input should occur in the driver class.
