Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows:  Income  Tax Due  $0 - $50,000 5%   $50,000-$100,000  $2,500 + 10% of (income > $50,000)  > $100,000  $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.

The atoms of different elements have different numbers of protons, neutrons and electrons. Electrons are negatively charged; protons are positively charged and neutrons have no charge. Write a definition for an atom class that contains: Fields for storing the numbers of protons, neutrons and electrons with appropriate visibility; Setter and getter methods for manipulating these fields, ensuring that the minimum value for electrons and protons is 1, and the minimum value for neutrons is 0; A constructor that initializes new objects of atom to be the smallest element (Hydrogen), for which the number of protons is 1, the number of neutrons is 0, and the number of electrons is 1. Write a new method for the atom class called ision that will return true or false, depending upon whether the atom is an ion. An atom is an ion if it is charged (i.e., if the number of electrons ≠ the number of protons). Write a new method for the atom class called getAtomicMassNumber that will calculate and…

This project has 3 classes which are already defined for you. Do not change any of these: Vehicle: an abstract class for any make and model of vehicle that can possibly travel some distance. LimitedRange: an interface for something that has a limit to the distance it can travel. Main: a test program which will work after you have written the code below. Your job is to write the following 3 classes so that this program produces the sample output shown at the end of Main.  Specifically you will need: ElectricCar: a vehicle with a limited range.  So it must be a subclass of Vehicle, and it must implement LimitedRange.  Thus it needs an instance variable for its range, and a travel method (required by Vehicle. Please use @Override) that outputs "Zoom!" if it has enough range to go the distance specified (and update its range).  It must have a constructor with 3 arguments as called by main. (Remember that the first line of the constructor must be a call to "super": Vehicle's constructor…

I've gotten stuck on this practice problem. I need help figuring this out.    You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the hungry level of the pet to 0 (Full) You must…

An airport van shuttles passengers between the terminal and the parking garage. After 4 trips, the tank is empty, and the van needs to drive to the gas station. After it has been refilled, it will drive to the terminal. The behavior of the van depends on two states: its location (terminal, garage, or gas station), and the tank level (empty or not). Complete the following class. The constructor yields a van in the garage with a full tank.

Part 1: Setting the turtle size when it is instantiated   Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following:   Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer.   Add an empty method body.   Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE.   In the method body of the one-parameter constructor do the following in this order:   Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter.   Compile the program and fix any…

You are given a template to help you follow the required structure. There are 10 files for the base and derived classes with specification and implementation files You are also given a driver MagicalCreaturesMain.cpp that you will complete. So 11 files in all. MagicalCreatureHeader.h  // given to you MagicalCreature.cpp  // given to you       ElfHeader.h     // given to you Elf.cpp            // you implement methods     DragonHeader.h    // given to you Dragon.cpp           // you implement methods   GoblinHeader.h   // given to you Goblin.cpp          // you implement methods   GenieHeader.h   // given to you Genie.cpp          // you implement methods Specifications: Here are five UML Diagrams: One for the Base class and the others for the derived classes. Use these along with the given template to complete the design of the classes and create the application. The template contains comments and notation as to where you need to fill in the code;…

For this assignment, you will develop the planning necessary for constructing a class that implements a Bag ADT in Java. Your program will store corresponding items for an On-Line Food Delivery Service. Specifically, your program should consider an item's name and price and manage the customer's shopping cart. The following are example values your class will be using for data: Customer Number = 1; item_Name="Can of Soup"; Price = $4.00; After selecting your values for data, what are the required operations that must be used to create the Bag Interface? Your deliverable will consist of the following: Pseudocode for your proposed program Flowchart of the operations of adding items to the shopping cart and removing items from the cart.

Create a base class and also a class that is derived from the base class. The base class needs to very generic, but would expect at least 4 data items. You must code getters and setters but it is OK to code in-line methods in the same file as this class. The derived class should use the public access specification. The code can be based on anything you like. Examples could be:  Base Class             Derived Class Music Instrument  Trumpet Cake                       Birthday or Wedding Cake Animal                    Bear, Cat, or more general such as mammal, fish, etcAssignment:1. In your main code, create an instance variable based on your base class and also an instance variable based on your derived class.2. Set variable values for each instance. ( Call the setters).3. Create a method that will display the values in both objects and call that method. This method should not be part of these classes.     For this step, you pass both instances ( as 2 parameters ) to the method and the…

If you fly in economy class, then you can be promoted to businessclass, especially if you have a gold airline card for privateflights. If you do not have a gold card, you can "reset" fromflight if the plane is full or you are late for check-in. All thesethe conditions are shown in the diagram below. Note that all statements(operators) are numbered. You run 3 tests:Test 1 - Gold card holder upgraded to business classTest 2 - Passenger without gold card remains in economy classTest 3 - Passenger who was "thrown" off the flightWhat is the statement coverage of these three tests?A. 60%B. 70%C. 80%D. 90%
