4. Economy: The constructor should invoke the super class constructor with the passed parameter ticketNo and ticketPrice. Override the cancelTicket method such that it displays a dialog box with the message: "Please note that there's no money refund for your ticket!". a. b. Override the loungeAccess method such that it returns false. d. Override the toString method such that it returns a String that begins with the word Economy, then the passenger info retrieved using the super class toString method. c. 5. FirstClass The constructor should invoke the super class constructor with the passed parameter ticketNo and ticketPrice. Then create a luggage object with default number of bags and weight for the extraluggage. Override the cancelTicket method such that it displays a dialog box with the message: ""Please note you have a refund amount ---ticketPrice-". b. Override the loungeAccess method such that it returns true. c. Override the toString method such that it returns a String that begins with the word FirstClass, then the a. е. passenger info retrieved using the super class toString method. Override the getLuggage method such that it returns a luggage object that consists of the summation of bags and weight in the luggage and extraluggage data fields. d. 6. Flight The constructor should initialize the ArrayList such that it's empty, and initialize all other data fields with corresponding arguments with same names. The method addPassenger should ask the user about the type of ticket to buy: Economy or FirctClass as in the following dialog box. a. b. Input ? Enter number of choice: 1.Economy class 2.First class OK Cancel Then create and add a passenger of the selected type to the ArrayList of passengers. If the user enters an option other than 1 or 2 (another number), or press cancel, the following dialog box should appear: Error X Sorry could not add passenger, incorrect input OK If the passenger is added successfully, the method returns true. Otherwise, it returns false. The method removePassenger should ask the user to enter the ticket number and the name of the passenger, then search for the passenger with the entered ticket number and passenger name (ignoring case sensitivity when matching names). If the passenger is found, it should invoke the cancelTicket method for that passenger, then remove him from the passengers ArrayList, then return true. If the passenger is not found, it should return false. C. d. Override the equals method such that two flights are equal if they are from the same origin airport and going to the same destination airport. Note that you should compare airports by invoking the equals method of the Airport class. e. Override the compareTo method such that it returns 1 if the first flight has more passengers than the second, O if they have the same number, and -1 if the first flight has less passengers than the second.
