Modify the Student class presented above as follows. ✓ Each student object should contain the scores for three (3) tests. (1) Provide a constructor that sets all instance values based on parameter values. (2) Overload the constructor such that each test score is assumed to be initially zero. (5) Provide a method called setTestScore that accepts two (2) parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score. (6) Provide a method called average that computes and returns the average test score for the student. (3) Modify the display method such that the test scores and average are included in the description of the students. (5) ✓ Implement the class to exercise the methods of Student. (8) NOTE WELL Ensure that your programs are documented (comments) as needed Make certain that your programs are debugged and working before submitting

1. Currently, a turtle is created and given a default size of 20. To change the size of the turtle its increase TurtleSizeBy5 and decrease TurtleSizeBy5 methods can be called. Add functionality so that a turtle can be created with a specified size. In the Doodle Turtle class do the following: a. Overload the Doodle Turtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. b. Add an empty method body. c. 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. d. In the method body of the one-parameter constructor do the following in this order: i. Call the initializeWith DefaultValues helper method. ii. Call the setSize method passing it the size parameter. e. Compile the program and fix any compilation errors before continuing.
Sally and Harry implement two different compareTo methods for a classthey are working on together. Sally’s compareTo method returns −1, 0, or +1,depending on the relationship between two objects. Harry’s compareTo methodreturns −6, 0, or +3. Which method is suitable?
Differentiate parameters passing method i.e, by line, by reference, by parameter? with suitable examples.
Under which of these conditions overloading a method would work (ie: the class will contain two methods with the same name)? O The methods have different numbers of parameters. O Two methods with the same name can never be included in the same class. O The methods have different parameter names. O The methods have different return types.

Create a class named Person.a. This class must have two variables to store name (string) and age (int). These variables should not be accessible from outside the class.b. Encapsulate the variables defined in item a with a property (an intermediate variable) so that they can be accessed from other classes. And after this step, use only intermediate variables that you defined for encapsulation within methods and other classes.c. Define a constructor method for this class. Code the constructor method to initialize the properties of the class at the time of object definition.D. Define a method called Print Info that will print the information of the class object on the screen in a proper format.
Dynamic Apex: You are working on the project in which you have to create the apex code in which your task is to define the objects dynamically by using the method argument which is api name in string and a map of string, string as a key value pair. For example: Assume the class name is Dynamic Test Class so the method call is: DynamicTestClass.modifySObject('Account', new Map{'Name' => Test'});
The Factory method design pattern is useful since it can be used to create new objects of a particular type dynamically. True False
Implement the inventory manager class. This class must have methods that do the following: Add a new item to the inventory manager. Remove an item from the inventory manager. Re-stock an item in the inventory manager. Display the items in the inventory manager. Search for an item in the inventory manager by at least two criteria (name, price, quantity, etc.). Part 3: Test the inventory manager class with a driver program or unit tests. This may be a console application.
Write a method for the farmer class that allows a farmer object to pet all cows on the farm. Do not use arrays.
This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player's score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class import pygame import abc import random class Drawable(metaclass - abc. ABCMeta): def --init(self, x- 0, y -0): self.x - x self.y - y self.position - (self.x, self.y) self.visible - False def setloc(self, p): self.x - p[0] self.y - p[1] def getloc(self): return(self.x, self.y) def getX(self): return self.x def getY(self): return self.y eabc.abstractmethod def draw(self, surface): pass eabc.abstractmethod def get_rect(self): pass
