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

Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…

Written in Python  It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods

1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information:  Lily, 5 years old Jacob, 2 years old Sugar, 8 years old Bush, 3 years old   2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why? 3. Fix this problem by implementing the toString method in the Dog class.   Dog Class:   public class Dog {   private String name;   private int age;    public Dog(String name, int age)   {      this.name = name;      this.age = age;   }   public void setName(String name)   {      this.name = name;   }    }

In python Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race.  The race function calls the move function for all of the racers in the BoatRace.  Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance.  If so, then return a list of all of the racers whose current_progress is greater than or equal to distance.  If no racer has finished the race then repeat the calls to move and check until at least one racer has finished the race. Examples: Copy the following if __name__ ==…

Write an Election class, in python that is used to record votes.

Create a Point classCreate a Point class as we did in the class. We'll use this to create Point objects that hold x,y coordinates of locations where we'll want to draw. Draw DotsWrite a drawDots(points) function that takes a list points as input and draws a dot on the drawing window for each Point. For example, you should be able to call your function as follows: >>> p = Point(10, 20) >>> q = Point(20, 30) >>> points = [p, q] >>> drawDots(points)

Create an application that reads a sequence of up to 25 names and postal (ZIP) codes for persons. Put the data in an object that can have a first name (string), last name (string), and postal code (integer). Assume that each line of input will have two strings separated by a tab character, followed by an integer value. After the input has been read in, print the list to the screen in the appropriate manner.
