Objectives To solve problems using ArrayLists ● To perform file I/O Introduction Instructions and Information There will be two classes implemented for this assignment: Hotel O HotelDemo Contains the data and some business logic related to an individual hotel O O Contains the main method Do not use the newer Java features for "unnamed classes" (with implicit class declarations) or instance main methods For this assignment, you will implement a class named Hotel. The class should contain: Data fields A private int data field named numRooms representing the total number of rooms available for the given Hotel A private int data field named numOccupied, representing the number of rooms currently occupied A private String data field named hotelName, with the name of the hotel Methods A no-arg constructor that creates a Hotel object with the name "Default Hotel", and 10 rooms total along with 0 rooms occupied A constructor that creates a Hotel object based on three parameters: hotelName, num Rooms, and numOccupied O These parameters correspond to the fields O The fields should be set to the corresponding parameter values Accessor (getter) and mutator (setter) methods for all data fields ● Input ● ● A getOccupancyRate method that returns the occupancy rate for the hotel O Occupancy rate = number of rooms occupied / total number of rooms The input will be obtained from a file, named input.txt. Each line will contain either one or three values. Each line represents a separate Hotel, whose data should be made into an object. If there's one value (meaning anything that doesn't have any commas in it - could be a string, integer, double, etc.), you just create a Hotel object using the no-arg constructor. If there are three values provided, you create a Hotel object, with the following conditions: O When you eventually display the value, you should display up to two decimal places Hint: The DecimalFormat class or using printf could help with this ■ Number of rooms must be at least 5 Number of occupied rooms cannot exceed the number of available rooms O If it does in fact do this for a given line, you should not create a Hotel object or add its reference to the ArrayList (see below) Regardless, if the input is a valid hotel, you should create the Hotel object and add the object's reference to an ArrayList of Hotel objects, maintained in the same file as main. Input Format If one value: Hints If three values: <some value, a number of string, no commas> Name, Number of rooms, Number of occupied rooms Specifically, a single line of example input might be: Billy Bob's Inn, 15, 5 Consider that the nextLine method of a Scanner can be used to read in the entire line of data as a String The String class has a method called split that will return a String array, with values separated by a delimiter O Default delimiter is space, but this can be changed Output As soon as the file is read into memory and the data is placed in the appropriate data structure(s), the following will be printed to standard output (the console), in general form: 2 <Hotel Name> : <occupancy rate> At the very bottom of the output, you should display the overall occupancy rate across all hotels that were read in from file (only count the valid ones, of course). Total occupancy: Example Sample Input File Bob's Hotel, 15, 5 0 <occupancy rate> John's Hotel, 20, 5 Hotel California, 100, 80 Snugglebear 66, 50, 50 Dumptruck Inn, 50, 100 (Note that line 2 should be default because there aren't three values, and the last line is invalid because the occupants outnumber the total number of rooms) Sample Output Note: Display the values as a percentage Bob's Hotel: 33.00% Default Hotel: 0.00% John's Hotel: 25.00% Hotel California: 80.00% Snugglebear 66: 100% Total occupancy: 71.79% (Total occupancy was calculated by summing all the total occupancy at each hotel, and the total available rooms, and then dividing number of occupied rooms by total number of rooms at each hotel - it only considered the valid hotels. So, this was 140/195). The default hotel had 10 rooms.
