- Assignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date createdNewspaperSubscriber class- create an abstract class named NewspaperSubscriber with attributes to contain the subscriber’s street address and the subscription rate. Include get and set methods for both these attributes. The set method for the rate is abstract. The setAddress method must prompt the user to enter the subscriber’s address through the use of a dialog box. Create a constructor for the base class. Create a toString() method that concaternates and returns the subscriber’s street address and rate for display. Create 3 child classes named SevenDaySubscriber, Weekday Subscriber, and Weekend Subscriber. Each child class has an additional attribute called subType, which is a String, that will store the type of newspaper subscription. Create a setType method that will set the type of subscriber as follows: “Seven Day”, “Weekday”, or“Weekend”. Create a setRate method for each child class that sets the rate as follows: a SevenDaysubscriber pays R18.00 per week for his newspapers, a…An interface is a collection of _______ that a class can implement
- Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…In order to extend a class, the new class should have access to all the data and inner workings of the parent class. True Falseclass City(object): county = "Lake" population = 3000000 def -_init__(self, name, state): self.name = name self.state = state def region(self): return "Midwest" a) create an instance of this object, called X, for Chicago, Illinois b) return the population of the instance X c) change the county of the instance X from Lake to Cook d) return the name of the state of the instance X d) call the method region() on the instance X
- This function is used to check whether an object is an instance of a specific class or a subclass of that class. a. isinstance b. isobject c. isreference d. _ _str_ _Circle ClassWrite a Circle class that has the following fields:• radius: a double• PI: a final double initialized with the value 3.14159The class should have the following methods:• Constructor. Accepts the radius of the circle as an argument.• Constructor. A no-arg constructor that sets the radius field to 0.0.• setRadius. A mutator method for the radius field.• getRadius. An accessor method for the radius field.• area. Returns the area of the circle, which is calculated asarea = PI * radius * radius• diameter. Returns the diameter of the circle, which is calculated asdiameter = radius * 2• circumference. Returns the circumference of the circle, which is calculated ascircumference = 2 * PI * radiusWrite a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJava
- Parking Ticket SimulatorFor this assignment you will design a set of classes that work together to simulate apolice officer issuing a parking ticket. The classes you should design are:• The Parkedcar Class: This class should simulate a parked car. The class's respon-sibilities are:To know the car's make, model, color, license number, and the number of min-utes that the car has been parkedThe BarkingMeter Class: This class should simulate a parking meter. The class'sonly responsibility is:- To know the number of minutes of parking time that has been purchased• The ParkingTicket Class: This class should simulate a parking ticket. The class'sresponsibilities areTo report the make, model, color, and license number of the illegally parked carTo report the amount of the fine, which is $2S for the first hour or part of anhour that the car is illegally parked, plus $10 for every additional hour or part ofan hour that the car is illegally parkedTo report the name and badge number of the police…We use the _____ operator to create an instance of (object in) a particular class.2. Car Class Write a class named Car that has the following data attributes: _ _year_model (for the car’s year model) _ _make (for the make of the car) _ _speed (for the car’s current speed) The Car class should have an _ _init_ _ method that accepts the car’s year model and make as arguments. These values should be assigned to the object’s _ _year_model and _ _make data attributes. It should also assign 0 to the _ _speed data attribute. The class should also have the following methods: accelerate The accelerate method should add 5 to the speed data attribute each time it is called. brake The brake method should subtract 5 from the speed data attribute each time it is called. get_speed The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method five times. After…
