Question
Develop a simple Hotel program. We will have two classes, a Hotel class representing an individual hotel and a Room class. The Hotel class will contain several Room objects and will have several operations. We will also have a driver program to test the Hotel class.
Build a Hotel class that will store information about a Hotel. It will include a name and location. It should also include an Array of instances of class Room to hold information about each room. It will also have a int called occupiedCnt that keeps track of how many rooms in the hotel are occupied. You must use an Array, you cannot use an ArrayList. Set the Array to hold 10 Room objects.
Build a HotelTest class to test your application. Your test class should not require any interaction with the user. It should verify the correct operation of the constructor and all public methods in the Hotel class. Create at least 5 rooms.
Specific Requirements for the Hotel Class:
The Hotel will have an addRoom method that will create each room with the required information: room number, bed type, smoking/non-smoking, and the room rate. Create at least 5 rooms with different characteristics. Each room will also have a boolean field called occupied attribute that will be set to false when the room is created. Don't forget to increment the numOfRooms instance variable. Example values for the rooms are:
101 queen s 100
102 king n 110
103 king n 88
104 twin s 100
105 queen n 99
Hotel
theRooms: Array Room[]
name: String
location: String
occupiedCnt: int
numOfRooms: int
Hotel()
Hotel(String,String)
isFull() : boolean
isEmpty() : boolean
addRoom(int,String,char,double)
addReservation(String,char,String)
cancelReservation(String)
findReservation(String): int
printReservationList()
getDailySales() : double
occupancyPercentage() : double
toString():String
Access and mutator methods for name and location.
isEmpty() %u2013 returns a boolean that is true if all the rooms in the hotel are unoccupied.
When the cancelReservation() method executes, the hotel will search for the name of the visitor in each room. If it is found, the occupied attribute will be set to false. In either case a message will state whether or not the reservation was cancelled. This method calls the private utility method findReservation()to scan the list of rooms looking for a guest by name. It will return the index of the room in the Array of rooms or NOT_FOUND if the room is not found, which will be declared as:
private static final int NOT_FOUND = -1;
printReservationList() will scan through all the rooms and display all details for only those rooms that are occupied. For example:
Room Number: 102
Occupant name: Pinto
Smoking room: n
Bed Type: king
Rate: 110.0
Room Number: 103
Occupant name: Wilson
Smoking room: n
Bed Type: king
Rate: 88.0
occupancyPercentage() will divide occupiedCnt by the total number of rooms to provide an occupancy percentage.
Hotel Name : Beach Marriot
Number of Rooms : 5
Number of Occupied Rooms : 1
Room Details are:
Room
roomNum: int
bedType: String
rate: double
occupantName: String
smoking: char
occupied: boolean
Room()
Room(int,String,char,double)
getBedType(): String
getSmoking(): char
getRoomNum(): int
getRoomRate(): double
getOccupant(): String
setOccupied(boolean)
setOccupant(String)
setRoomNum(int)
setBedType(String)
setRate(double)
setSmoking(char)
isOccupied(): boolean
toString(): String
isOccupied() method returns true if the room is occupied, false otherwise.
Several accessor and mutator methods for the Room class.

name: String
location: String
occupiedCnt: int
numOfRooms: int

Access and mutator methods for name and location.
Explanation / Answer
The code was too long to solve. It took time. But now, every single line of code is validated and checked.
Every single method is written properly and the Driver class or the test class check all the methods (skips not even a single one.) Here is the sample output first followed by the code.
Sample output
Adding rooms to the hotel
There are total 5 rooms in the hotel
===================================================================
Checking if all the rooms in the hotel are empty
Yes, all the rooms in the hotel are empty
===================================================================
Looking for reservation in the hotel
Reservation 1
Yes, there is room available of your choice
Reservation is made
Reservation 2
No match found
Reservation is not made
Reservation 3
Yes, there is room available of your choice
Reservation is made
===================================================================
Printing details of all the rooms which are occupied
Room Number : 102
Occupant Name : Coffey
Smoking room : n
Bed Type : king
Rate : 110.0
Room Number : 104
Occupant Name : Brian
Smoking room : s
Bed Type : twin
Rate : 100.0
===================================================================
Checking if the hotel is full or not
The hotel is not full. We can accomodate few more people.
===================================================================
Find the total sale for today
Total sale for today is $:210.00
===================================================================
Lets check the occupancy percentage
Hotel occupancy percentage for today is :40.00%
===================================================================
Cancel the reservation for Brain
Reservation in the name of Brian is cancelled
===================================================================
Now that Brian's reservation is canceled, his details should not be printed
Printing details of all the rooms which are occupied
Room Number : 102
Occupant Name : Coffey
Smoking room : n
Bed Type : king
Rate : 110.0
===================================================================
All the methods are properly checked.
