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
O self.d, return, self
O self.d, return, self.d
O return, print, self.n
O self.d, print, self.n
O n.getnum(self), return, d.getd(self)

Car Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…

JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString().

INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…

in C# i need to Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf. Create an interface named ITurnable that contains a single method named Turn(). The classes named Page, Corner, Pancake, and Leaf implement ITurnable. Create each class’s Turn() method to display an appropriate message. For example: The Page’s Turn() method should display You turn a page in a book. The Corner’s Turn() method should display You turn corners to go around the block. The Pancake's Turn() method should display You turn a pancake when it's done on one side. The Leaf's Turn() method should display A leaf turns colors in the fall.
When a method receives an object as an argument, does the method have access to the actual object or a copy of the object?
