. Exercise # 2: Implement a class Portfolio. This class has two objects, checking and saving, of the type bankAccount that was developed in the worked example. Initialize the 2 bank accounts with 0 initial balance. . Implement four methods • def deposit (self, amount, account) • def withdraw (self, amount, account) • def transfer (self, amount, account) • def getBalance (self, account) • Here the account string is "S" or "c" for Saving and Checking, respectively. For the deposit or withdraw, it indicates which account is affected. For a transfer , it indicates the account from which the money is taken; the money is automatically transferred to the other account. • To test your class: . create one Potfolio object • deposit 10000 in its checking account . transfer 5000 from checking account to saving account . withdraw 2500 from checking account • display the balance of both accounts A run for the above test program will result in the following output 5000.0

The Huntington High School basketball team has five players named Art, Bob, Cal, Dan, and Eli. Implement the BarChart class which accepts the number of points scored by each player in a game and displays a bar chart that illustrates the points scored by displaying an asterisk for each point. The output looks similar to the chart in Figure 6-34.   import java.util.Scanner; public class BarChart {     public static void main (String[] args) {         Scanner input = new Scanner(System.in);         int artPoints;         int bobPoints;         int calPoints;         int danPoints;         int eliPoints;         System.out.print("Enter points earned by Art >> ");         artPoints = input.nextInt();         System.out.print("Enter points earned by Bob >> ");         bobPoints = input.nextInt();         System.out.print("Enter points earned by Cal >> ");         calPoints = input.nextInt();         System.out.print("Enter points earned by Dan >> ");…

a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type:       1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z. Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)

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)

Write a program to test the Book class using C++. Create objects and use the print function in the objects to display information.

Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

17. Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message in half and then take characters from each half alternately. For example, if the message is abcdefghi, the halves are abcde and fghi. The shuffled message is afbgchdie. (Hint: You may wish to define a private method that performs one shuffle.)

Can you please help me with this, its in java. Thank you.   Write classes in an inheritance hierarchy Implement a polymorphic method Create an ArrayList object Use ArrayList methods For this, please design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and frozen yogurts. Present the user with the following menu options: Actions: 1) Add a salad2) Add a sandwich3) Add a frozen yogurt4) Display an item5) Display all items6) Add a topping to an item9) QuitIf the user does not enter one of these options, then display:Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input.   All menu items have the following: Name (String) Price (double) Topping (StringBuilder or StringBuffer of comma separated values) In addition to everything that a menu item has, a main dish (salad or sandwich) also has: Side (String) A salad also has: Dressing (String) A sandwich also has: Bread type…
