Question
Write code for an Invoice class for a car sale. Printing an object of the Invoice should print thedetails about the seller, the buyer, the dealer, the date of transaction, the car being sold, the purchase and selling price, the commission earned by the dealer, sales tax, and the total price of the car (calculated given the details in Question 3 part 3). A generation of the invoice object should set the isSold variable of the car class to true. You do not need to write code for any other classes
Syntax of the Q3 code is given below:
import java.util.*;
class Car{ //class car
String[] name;
int reg_number,eng_number, chassis_num,status;
String[] city, model, color, date_reg,date_arr,type;
float price;
float abstract calculate (float price);
}
class Dealer extends Car{ //inherits from Car
String[] deal_name,…
Suppose a parent class has a few methods that the child would like to use, but the methods are not appropriate for the child. What can the child do to make the methods 'usable' for itself?
Write classes that could be used in a system that manages vehicles in a public transportation system.
You will write classes to represent a TransitVehicle, Bus, and SubwayCar. The information about the classes is below.
Step 1: Plan Your Class Design
Before you start to code, decide how to design your classes. Which class should be the parent? the child? What variables or methods belong in each class?
Step 2: Write the Core Class Components
Write the three classes. Each class must have all of the following.
Important: a class can have a method directly (meaning written into the code) or indirectly (meaning inherited from a parent). Either of these counts to meet the requirement.
instance data variables
transit vehicles are described by an id that contains letters and numbers and a description of the route
buses are described by an id, route, and the number of miles per gallon (without decimals)
subway cars are described by an id, route, and whether or not the car goes underground…

- Draw the UML diagram for the class. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this account was created.arrow_forwardYour assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…arrow_forwardIn this activity, we are going to plan out and write a class definition that stores information for a book. Let's say we want to store the following information about this book: The book's name The book's author(s) (a book can have more than one author) The book's publisher The book's ISBN number The book's price The book's year of publication First, answer the following questions before the design: 1. What is a suitable name for this class? (Pick a name that best describes it).arrow_forward
- Write the Movie class. The UML diagram of the class is represented below: 1. Implement the class strictly according to its UML one-to-one (do not include anythingextra, and do not miss any data fields or methods). 2. Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.arrow_forwardNow we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…arrow_forwardDesign and implement an object-oriented program for displaying a deck of cards. Each card will have a value ranging in order from 1 for an ace, 2 for a two, and so on up to and including 11 for a jack, 12 for a queen, and 13 for the king. The focus of the exercise is to create three classes that represent a card, deck, and hand using composition.arrow_forward
- Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and array of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array.arrow_forwardWrite a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer numberand a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstrate an instance of the Customer class in a simple program.arrow_forwardWrite a class named Person with data attributes for a person’s name, address, and telephone number.

- Write and document the definition for the Product class. The Product class represents an item that would appear for sale on a Web site or in a department store (like a toaster). Each Product object has three instance variables: description, productNumber and price. The class has one constructor that takes three parameters in the order productNumber, description and price. The class has one accessor method named getCost(int qty) which returns the price for qty items of the Product. The class has two mutator methods—setPrice() and setDescription()—that modify the corresponding instance variables. The class has a toString() method that returns the Product as a String in the form: 34567: Small Toaster, $ 17.95. Note: use concatenation to construct the returned string. Do not use the String.format() method to format the returned value.arrow_forwardWrite a class named Person with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the Customer class in a simple program. All your programs will be modular. It will have the main() method that is executed first. Submit code that has no syntax error. And test your code, so as to not have logic errors. Each program must contain your name in the comments section and the date you created the code.arrow_forwardIn your own words, describe the relationship between classes and objectsarrow_forward
