Class Hotel (30 marks): Open the Java file Hotel.java that is provided. Note that every hotel is a building with some extra features. You must consider this fact in the implementation of the class Hotel. Complete this Java class using the following specifications: Every hotel has (4 marks) name rate one or more owners one or more rooms Provide the default constructor for the class, which only calls the default constructor of its superclass. (1 mark) Provide the second constructor for the class, with five parameters, hotel name, list of the hotel owners, year of built, number of floors, and hotel rate, which initializes the corresponding instance variables. Note that the proper constructor of the superclass must be called in this constructor. Also, the list of the hotel rooms must be initialized. (4 marks) Provide getter methods for hotel name and owners. (2 marks) Provide a getter method, getRooms, which returns the list of the hotel rooms as an ArrayList of rooms. (1 mark) Provide a getter method, getRoom, with one parameter, room number, which returns the corresponding room as its return type, and otherwise null. (1 mark) Provide a method, addowner, which adds one owner to the hotel's owners list. (1 mark) Provide a method, addRoom, which adds a new room to the hotel. (1 mark) Provide a method, reserve, with four parameters, room number, start date, end date, and guest. It will first find the room using one of the above methods. If it finds the room, then it simply calls the reserve method of that room, receives the reservation number and returns it. If the room is not found, it returns zero, which means the reservation was not successful. (4 marks) Provide a method, cancel, with one parameter, reservation number. It should find the room that has this reservation numbers. If it finds the room, then it will call the cancel method of that room with the reservation number given, and then returns true. Otherwise, it returns false, which means the cancellation was not successful. (3 marks) Override the tostring method, such that it returns a string including the hotel information, with the format like example below. It shows the hotel information, followed by the rooms' information. (3 marks) Hotel Baba Mama, 3.5 stars.
