Customer This class should now implement the Comparable interface. Customer instances should be ordered by their last name, then first name, and finally the name of their associated building. toString() - Add this method that returns a String with the following format: <lastName>, <firstName> Reading This class should now implement the Comparable interface. Reading instances should be ordered by their timestamp. XmlHandler The following methods should be updated: startElement() - The handler logic should be modified such that it can now create and associate Customer, Building, Room, Device, and Reading objects. endElement() - Modify this method such that the current customer instance is added to the ArrayList of customers when a closing customer element is encountered.

2. You are creating a game that has the character go through a maze. Some walls are visible, but some are invisible. In other words, when the code tries to access some wall's Draw behavior, it will either do something useful or do nothing. Which pattern would be helpful for the drawing scenario? Options: Proxy, null object, Adapter, Decorator 3. You are developing an application that accesses a storage service for the customer. In some cases, you want to check the customer's payment status before actually accessing the storage. What design pattern would be best at providing this kind of control? Options: Proxy, null object, Adapter, Decorator
TechPreferences Object: let user TechPreferences = { preferredDatabase: "MongoDB", backendFrameworks: ["Express.js", "Django"], frontend Frameworks: ["React", "Angular", "Vue.js"], mobileFrameworks: ["Flutter", "React Native"], preferredIDE: "VS Code", continuousIntegration: true, }; Write a JavaScript function to process the information in "userTechPreferences" and answer the following: Display the person's preferred database. Identify and display any backend frameworks used by the person. Output the frontend frameworks the person is familiar with. Create a list of mobile frameworks the person is interested in. Display the preferred Integrated Development Environment (IDE). Check if the person uses continuous integration and display the corresponding message.
4. Be able to save a FriendsDB to a file. Add a method save() to the FriendsDB class, which takes a filename as an argument and saves all of the friends in the database to the specified filename. The file will contain one line per friend in the database, and each line of the file will contain that friend's name, followed by a tab, followed by their height, a tab, and then each of their favorite foods (separated by tabs), and finally a newline character. So for example a FriendsDB file with two friends, bimmy (height 60, favorite foods "falafel" and "vegemite") and eliza (height 170, no favorite foods) would contain lines equivalent to the following two strings. "bimmy\t60\tfalafel\tvegemite\n", "eliza\t170\t\n"|
Now, in order to make all of this legal, we must have a way to compensate the musical artists for their hard work and wonderful music. An artist should receive 25 cents each time one of their songs is downloaded. Hence, for each artist, we will keep track of how much money in royalties they have. Add the following attributes to the MusicExchangeCenter class: royalties - a HashMap with the artists' names as the keys and the values are floats representing the total amount of royalties for that artist so far. It should only contain artists who have had songs downloaded. You will update this HashMap later. downloadedSongs - an ArrayList containing all of the songs that have been downloaded. This list will, in general, contain duplicate Song objects. Write a method in the MusicExchangeCenter class called displayRoyalties(0 that displays the royalties for all artists who have had at least one of their songs downloaded. It should display a two- line header and then one line per artist showing…
In this project you will implement a student database using JavaFX. A GUI should be used as the program's interface. This program must consist of two classes. (1) The first class should define the GUI and handle the database interactions: a. Combo box should allow the user to select one of the four database actions (Insert, Delete, Find, and Update). b. The database should be implemented as a HashMap, with the ID field as the key and a student record consisting of a name and major as the value. c. The operation should be performed when the user clicks the Process Request button. d. If the user attempts to insert a key that is already in the database an error message should be displayed using a JOptionPane message dialog box. e. If the user attempts to delete, find or update a record that is not in the database, a message should also be displayed. f. After each successful operation is completed a JOptionPane window should be…
Question 6: You're the lead programmer on the new game "Asteroids War" where the player flies around a fictitious solar system, hauling asteroids back to the market to sell. You need to write a system for storing the thousands and thousands of asteroids in "Asteroid Farmer" so that each asteroid has: - A unique location - A unique rotation - A size - A shared mesh & texture (is one mesh/texture combo will be used for all asteroids) The player can travel at extreme speeds, approaching the speed of light, and therefore we need to be able to load the asteroids quickly & efficiently without running out of memory. Describe a memory management system for storing the thousands and thousands of asteroids in "Asteroid Farmer". Solution: Question 7: Continuing with Asteroids War", the player can sell the asteroids they haul back to the market, and they receive credits based off the size and chemical makeup of the asteroid. The player doesn't know the chemical makeup of the asteroid before…
Create a program that uses classes, polymorphism, and enums to monitor blizzards in Europe, with class members including the blizzard name, location, and snowfall amount, with a continuous menu to update, delete, display, search and add data stored in a collection. The application should have a menu that allow users to: • Add a new item to the collection. • Display all the items in the collection. • Search for a specific item. • Exit the application by pressing 0. The application should also display any error messages if the user enters invalid input. Coding Requirements: 1. Demonstrate applied use of foreground color and change in console title 2. Classes created and apply generics, abstract, and polymorphism
In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called “state”) do you need to keep track of? Alternatively, what does a date have? (“has a” == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format…
