Imagine that you want to define a class for fractional numbers, e.g., %4. Fill in the three blanks in the following code to make it a correct definition of a Fraction class. class Fraction: def _init_(self, numerator, denominator): self.n = numerator = denominator def _str_(self): (str(self.n) + "/" + str(self.d)) def getnum(self): return(self.n) def setnum(self, numerator): self.n = numerator def getden(self): return(self.d) def setden(self, denominator): = denominator self.d, return, self self.d, return, self.d return, print, self.n self.d, print, self.n

Write a code for a banking program.a) In this question, first, you need to create a Customer class, this class should have:• 2 private attributes: name (String) and balance (double)• Parametrized constructor to initialize the attributes• Methods:i. public String toString() that gives back the name and balanceii. public void addPercentage; this method will take a percentage value andadd it to the balanceb) Second, you will create a driver class and ask the user to enter 6 customers’ informationand then you will create an array of Customer objects.c) Then you use this array used for various operations as shown in the output.• Using the array of customer objects, you need to search for all customers whohave less than $150• Using the array of customer objects, you need to get the average balance of thebalances in this array• Using the array of customer objects, you need to get the customer with thehighest balance and lowest balance• Using the array of customer objects, you need to show all…
Use Python Programming Language Write code that defines a class named Animal: Add an attribute for the animal name. Add an eat() method for Animal that prints ``Munch munch.'' A make_noise() method for Animal that prints ``Grrr says [animal name].'' Add a constructor for the Animal class that prints ``An animal has been born.'' A class named Cat: Make Animal the parent. A make_noise() method for Cat that prints ``Meow says [animal name].'' A constructor for Cat that prints ``A cat has been born.'' Modify the constructor so it calls the parent constructor as well. A class named Dog: Make Animal the parent. A make_noise() method for Dog that prints ``Bark says [animal name].'' A constructor for Dog that prints ``A dog has been born.''

This program should be written in Java: Hamburger Joint: Hamburger ClassWrite a Hamburger class with the following six attributes: • bun - the type of bun the burger will be on • patties - the number of patties on the burger • cheese - whether or not the burger will have cheese • price - the price of the burger • toppings - an array of five toppings; it will need to start empty Write getters/setters for all attributes except the toppings array. Your constructor should create a single on white with no cheese and no toppings with a price of $2.99. Your class should include the following methods in this order, please: addCheese - this method has no parameters that adds cheese to the burger and increases the price by 75 cents superSizeIt - this method has no parameters and adds a patty to the burger and increases the price by 1.50 addToppings - this method would present the user with at least five toppings (your choice) stored in an array of String objects.

write in java Write a CashRegister class that can be used with the RetailItem class that you wrote inChapter 6’s Programming Challenge 4. (in the attachments) The CashRegister class should simulate the sale ofa retail item. It should have a constructor that accepts a RetailItem object as an argument.The constructor should also accept an integer that represents the quantity of items beingpurchased. In addition, the class should have the following methods:• The getSubtotal method should return the subtotal of the sale, which is the quantitymultiplied by the price. This method must get the price from the RetailItem objectthat was passed as an argument to the constructor.• The getTax method should return the amount of sales tax on the purchase. The salestax rate is 6 percent of a retail sale.• The getTotal method should return the total of the sale, which is the subtotal plus thesales tax.Demonstrate the class in a program that asks the user for the quantity of items being purchased,and…

JAVA PROGRAMMING Write two java files for this assignment: Circle.java, and Main.java. The Circle.java file will create an actual class. The Circle class: MEMBER VARIABLE double radius double x double y Eight methods: Six of the methods are simple: getter’s and setter’s for x, y, and radius. There should also be a getArea method that returns the area (derived from the radius) A doesOverlap method. This method should accept a Circle as an argument, and return true if this circle overlaps the circle that the method was invoked on. [Note: two circles overlap if the sum of their radius' is greater than or equal to the distance between their centers.] void setX(double value) double getX() void setY(double value) double getY() void setRadius(double value) double getRadius() double getArea() boolean doesOverlap(Circle otherCircle) second class will be the typical replit Main class, with its static main method .It should contain code that tests the Circle class. submit code that…
