Make a class names Foo Add a class variable to foo called x and initialize it to 5 Add an instance variable to foo called y and initialize it to 100 Make an instance of the class, call it f Using f, print out the value of x Print out the value of y Hint: remember that class variables are the ones where their value is the same for all instances/clones. And instance variable (which you declare inside the __init__ method with the self. preface, are unique to each clone. When you print a class variable the proper way is to use classname . (for example Foox) and when you print an instance variable you use the instance handle (for example f.y.)

Create a class Divide with the following fields, constructors and methods:Fields: create two double fields called numerator and denominator Constructors:- a no-argument constructor- a constructor with two parameters Methods:- write a getter to return the result of numerator divided by denominator- Create 4 overloaded calculate methods. Note: Division would be numerator divided by denominator 1. method receives two double parameters and returns the result of the division as double 2. method receives two integer parameters and returns the result of the division as double 3. method receives one integer parameter and another as double parameter and returns the result of the division as int 4. method receives two String parameters and returns the result of the division as int Create a demo class to test the two constructors, all the methods and display the returned values. You can hard code the parameters values when calling the constructor and the methods.

javacoding please thank you!

fast in pyth please

1. Create the main method using pythone to test the classes. #Create the class personTypefrom matplotlib.pyplot import phase_spectrum class personType: #create the class constructor def __init__(self,fName,lName): #Initialize the data members self.fName = fName self.lName = lName #Method to access def getFName(self): return self.fName def getLName(self): return self.lName #Method to manipulate the data members def setFName(self,fName): self.fName = fName def setLName(self,lName): self.lName = lName #Create the class Doctor Type inherit from personTypeclass doctorType(personType): #Create the constructor for the doctorType class def __init__(self, fName, lName,speciality="unknown"): super().__init__(fName, lName) self.speciality = speciality #Methods to access def getSpeciality(self): return self.speciality #Methods to manipulate def setSpeciality(self,spc):...

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...

The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }

Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
