Hello, I need help programming a python code for my homework assignement. Any help would be appreciated. Thank you
1. Create a class called Account that
a. includes one instance variable represents the account balance
b. does initialize the account balance
c. does provide two methods. Method Credit should add an amount to the current
balance. Method Debit should withdraw money from the Account
d. does provide a string representation when we call print on it, i.e., when
print(account1) is called.
2. Define class SavingsAccount that inherits from Account class and
a. includes an instance variable indicating the interest rate (percentage) assigned to
the Account.
b. does initialize its property, inherited from Account and defined in SavingsAccount, to
the values given at the time of instantiation.
c. provide method CalculateInterest that returns the amount of interest earned by an
account. Method CalculateInterest should determine this amount by multiplying the
interest rate by the account balance.
d. does provide a string representation when we call print on it
3. Write a test class named AccountTest that demonstrates class Account’s capabilities and
a. has a method "main" to test the Account and SavingsAccount classes
b. The main method must instantiate the class into objects and test all of its methods
in to get all instructions to run.
c. call AccountTest.main() to run the program

- Instructor note: This lab is part of the assignment for this chapter. HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss. Java Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0. Ex: If the random object is created with a seed value of 2 and the input is: 3 the output is: Heads Tails Heads Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…arrow_forwardJAVA.

- 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…arrow_forwardJAVA PROGRAMMING Create a class named "Circle" that has attributes radius, area and circumference and make the attributes private.

The switch statement has the following syntax: switch (variable) { case value1: // Code that should execute when variable==value1 break; // this prevents it from automatically going to the next case case value2: // Code that should execute when variable==value2 break; // this prevents it from automatically going to the next case default: // Code that should execute when variable has a value that didn't match the above }arrow_forward
