You need to program the following classes: MyTravel.java - Class storing the "main" method. Travel.java - Superclass storing common travel information. AirTravel.java Subclass of Travel specific for air travel. LandTravel.java - Subclass of Travel specific for load travel. Notes that you may add additional methods to any of the classes, but you must follow the specified structure. B.1 Travel Abstract Class Abstract class Travel contains: A protected String data field travelType, either "Air" or "Land". A protected String data field country, e.g. "France", "England", etc. A protected String data field city, e.g. "Paris", "London", etc. A protected String data field travelDate, e.g. "Jan 30 2022". A protected String data field returnDate e.g. "Feb 20 2022". A protected int (or Integer) data field days, e.g. 21. A protected String data field hotel, e.g. "Hilton", "Marriott", etc. A protected double (or Double) data field named cost, e.g. 1500. A private int (or Integer) data field travelMileage, e.g. 2000. A constructor method initializing each data field. Methods set and get for each data field. A print method printing the values of all data fields in the class. B.2 AirTravel Class Class AirTravel contains: A private String data field airline, e.g. "Delta", "United", etc. A private String data field travelRefNumber, e.g. "A123456", etc. A constructor method initializing each data field. Methods set and get for each data field. A print method printing the values of all variables. B.3 Land Travel Class Class Land Travel contains: A private String data field carType, e.g. "Gas", "Electric". A constructor method initializing each data field. Methods set and get for each data field. A print method printing the values of all variables. B.4 MyTravel Class Class MyTravel contains: An "init" method where all travel objects are initiated from data read from the input file and stored inside an array called my Travel. A "print" method printing all the data fields for each travel object, the total travel days and total cost. The "main" method that calls the init and print methods. B.5 ReadTextFile Class The class "ReadTextFile.java" is given to read individual lines from the text file and assign them to objects. B.6 Text Files The input text file "travel.txt" is given consisting of a numerical line stating the number of travel objects to be read from the file. Each line consists of data separated by commas representing each data field for each object. The number of entries in the input file may change when testing the final code, although it will keep the following format for the file: number of travel objects travell_datal, travell_data2.... travel2_datal, travel2_data2, ... travelN_datal, travelN_data2,...
