First, implement a python class called Student. This class should store 2 variables, name and grade. Later, implement a class called Classroom. The constructor of this class should input the list of students in this classrom. This class should also contain 3 methods, add_student, remove_student and calculate_stats. As the names suggest, add_student method should input a Student object and add that to its' already existing student list, remove_student must input a full name(string) and delete the student with the provided name(you can assume no 2 students have the same full name). Finally, calculate_stats method must calculate and print the following statistics of the grades: 1. The name of the student with highest grade and the grade itself. 2. The name of the student with lowest grade and the grade itself. 3. The average grade

Complete the Course class by implementing the printRoster() method, which outputs a list of all students enrolled in a course and also the total number of students in the course. 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: toString() returns a String representation of the Student object.) Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA then the program output is: Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4 course.java import java.util.ArrayList; // Class representing a studentpublic class Course { private ArrayList<Student> roster; // Collection of Student objects public Course() {…
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…

in PYTHON, please Given a base Plant class and a derived Flower class, write a program to create a list called my_garden. Store objects that belong to the Plant class or the Flower class in the list. Create a function called print_list(), that uses the print_info() instance methods defined in the respective classes and prints each element in my_garden. The program should read plants or flowers from input (ending with -1), add each Plant or Flower to the my_garden list, and output each element in my_garden using the print_info() function. Note: A list can contain different data type and also different objects. Ex. If the input is: plant Spirea 10 flower Hydrangea 30 false lilac flower Rose 6 false white plant Mint 4 -1 the output is: Plant Information: Plant name: Spirea Cost: 10 Plant Information: Plant name: Hydrangea Cost: 30 Annual: false Color of flowers: lilac Plant Information: Plant name: Rose Cost: 6 Annual: false Color of flowers: white Plant…
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…
In Java, please. Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. 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. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int…
Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.
Write a Java program that prompts a user for vehicle data and stores it in a linked list, and then sorts the list in ascending order based on miles-per-gallon and writes the sorted data to a text file, you can follow these steps: Create a class named Vehicle with private fields: make (String), model (String), and milesPerGallon (double). Include getters and setters for these fields. Implement the Comparable interface for Vehicle class and override the compareTo() method to compare vehicles based on their milesPerGallon. Create a main class (for example, VehicleDriver.java) to handle user input and perform the necessary operations. Inside the main method, create a BufferedReader object for user input. Prompt the user to enter the number of vehicle data they want to enter and store it in a variable (for example, nVehicles). Use a loop to iterate nVehicles times and prompt the user to enter make, model, and miles per gallon for each vehicle. Create Vehicle objects using the input data…
) Modify the BookStore and BookSearchEngine classes explained in the class to include the following additional methods and test them:a) A method returning the book with the lowest price in the library.b) A method searching the library for Books of a given author and returning an ArrayList of such Books. c) A method returning an ArrayList of Books whose price is less than a given number.
Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…
In F3, students will be tasked with taking input from a file to create an *Array* of FeetInches (2 parameters). When all the FeetInches have been stored, any FeetInches at least 1 foot will be converted and added to an *ArrayList* of Circles (one parameter). Students will then complete the compareTo method found in the Circle class, sort the ArrayList of Circles, and then output the radius' of the new circle. The first integer in the file input will tell us how many FeetInches objects will be made using the fileInput, and the numbers after are the data for those Objects. Use this first integer in your for Loops. A template with main, Circle, and FeetInches class, as well as the file input, is attached below. Please follow along with comments and reach out if you have any questions. package f3_template; public class Circle implements Comparable <Circle>{//attribute private int radius; //constructorspublic Circle(){radius=0;}public Circle(int r){radius=r;}//accessorspublic…
