Simple Hotel Reservation System - OOP Lab

Implement using Java, a simple hotel reservation system with the following 4 classes: class Room , class SingleRoom, class DoubleRoom and class Hotel, Your implementation should ensure encapsulation.

Class Room is abstract each room has:

• An integer variable roomNumber
• A boolean variable reserved representing if the room is reserved or not.
• A constructor that receives the roomNumber for initialization of the roomNumber instance variable
• Accessor method for instance variables.
• Mutator method for reserved
• An abstract method : public abstract double getPrice( )

Class SingleRoom which extends Room such that:

• each single room has a constructor that receives the roomNumber for initialization of the roomNumber instance variable
• Implements method getPrice( ) defined in class Room by returning

Class DoubleRoom which extends Room such that:

• Each double room has a constructor that receives the roomNumber for initialization of the roomNumber instance variable
• Implements method getPrice( ) defined in class Room by returning

Class Hotel, each hotel has:

• A String variable name
• A variable rooms of type: Room [ ] representing the hotel rooms
• A constructor that receives the name , rooms for initialization of instance variables
• Accessor methods for instance variables.
• A method public boolean isFull( ) which returns true if all the hotel rooms are reserved, otherwise returns false.
• A method public boolean reserveRoom(Room room) ,which if room is not reserved , set the reserved variable of room to true and returns true otherwise returns false.

Write a test program that creates

• 10 rooms (5 single rooms and 5 double rooms)
• A hotel with name my hotel and has 10 room which are created
• Reserve room 1,3,5,10 and 6 if not reserved
• Reserve room 1, if is already reserved then reserve room
