Question 4: Elections rite an Election class, used to record votes. The class has the following methods: • vote(c) : records a vote for candidate c. • total_votes(): returns the total number of votes. • winner(): returns the set of candidates with maximal votes. Normally there is only one, but there could be a tie, in which case you re the set of tied candidates. Return None if no votes have been cast. • margin(): returns the margin of victory, that is, the number of votes separating the fist from the second candidate. This can be 0, ine of a tie. If there is only one candidate, you can answer with the number of votes for the candidate. If no votes have been cast, return

In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
10.5 LAB: Count probations (EO) Students are put on probation if their GPA is below 2.0. Complete the Course class by implementing the countProbation() method, which returns the number of students with a GPA below 2.0. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Hint: Refer to the Student class to explore the available methods that can be used for implementing the countProbation() method. Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.2 GPABrenda Stern with 1.2 GPALynda Robison with 3.3 GPAJake Flynn with 1.8 GPA then the countProbation() method returns 2 and the program output is: Probation count: 2 Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student…

Assignment 4 - Car Maintenance This assignment will assess your understanding of void and value returning static methods. Your cousin owns an automotive maintenance shop that performs routine maintenance on cars. He has asked you to write a program that will provide a list of services (and their respective prices) to users and allow them to choose any, or all, services they would like and display the final price, including a 28% labor charge, a 9% markup if the car is an import, and an 8% sales tax. Task To accomplish the above, do the following: • Write the two methods outlined below. • Test your program and screenshot your successful test. carMaintenance method This method should accept the make of the car as a parameter (e.g., BMW, Ford, Ferrari, etc.). It should display the services and their prices as follows: Services: Oil Change, Tune up, Brake Job, Transmission Service, respectively: 59.99, 111.99, 189.99, 149.99 These should be stored in parallel arrays. Ask the user to…
• RectangleTest class:o Perform the following actions in the main method:▪ Create an object named r1 of the Rectangle class using the default constructor.▪ Using the set methods, initialize r1 to have width 3.0 and length 5.2.▪ Use the printDimensions method to output all the data (width & length) related to r1.▪ Create another object named r2 of the Rectangle class with width 2.6 and length 5.4using the overloaded constructor.▪ Print out r2 (width & length) using the get methods.▪ Print out the area and the perimeter of r1 using the calculateArea andcalculatePerimeter methods.▪ Print out the area and the perimeter of r2 using the calculateArea andcalculatePerimeter methods
Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…
Write in python. Write a class named Employee that has **private** data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.Write a separate function (not part of the Employee class) named **make_employee_dict** that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.For example, it could be used like…
Fibonacci A fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on… For this, you will implement a class that takes a positive integer (n) and returns the number in the nth position in the sequence. Examples When n is 1, the returned value will be 0. When n is 4, the returned value will be 2. When n is 9, the returned value will be 21. come up with the formula and base cases Implementation Create a class Fibonacci with a public static method getValue. Create a Main class to test and run your Fibonacci class.
