- Employee class Write a Python program employee.py that computes the cumulative salary of employees based on the length of their contract and their annual merit rate. Your program must include a class Employee with the following requirements: Class attributes: name: the name of the employee position: the position of the employee start_salary: the starting salary of the employee annual_rate: the annual merit rate on the salary contract_years: the number of years of salary Class method: get_cumulative_salary(): calculates and returns the cumulative salary of an employee based on the number of contract years. Round the cumulative salary to two digits after the decimal point. Example: If start_salary = 100000, annual_rate = 5% and contract_years = 3: Then the cumulative salary should be : 100000 + 105000 + 110250 = 315250 Outside of the class Employee, the program should have two functions: Function name Function description Function input(s) Function output(s) / return…Python Code please Point of Sale Write a program that will manage the point of sale in a store.

- Course Title: Modern Programming Language Please Java Language Code Question : Create a class called with your 18Arid2891, as Invoice18Arid2891, that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a test application named InvoiceTestMJibranAkram that demonstrates class Invoice’s…A. Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method…class TicTacToePlayer: # Player for a game of Tic Tac Toe def __init__(self, symbol, name): self.symbol = symbol self.name = name def move(self, board): move = int(input(self.name + " make your move 1-9:")) move -= 1 y = move % 3 x = move // 3 board[x][y] = self.symbol def is_symbol(self, symbol): if symbol == self.symbol: return True class TicTacToe: # Game of TicTacToe in a class! def __init__( self, p1_symbol="X", p2_symbol="O", p1_name="Player1", p2_name="Player2" ): self.p1 = TicTacToePlayer(p1_symbol, p1_name) self.p2 = TicTacToePlayer(p2_symbol, p2_name) self.board = [[" " for x in range(3)] for x in range(3)] def play_game(self): turn = 0 winner_symbol = False while not winner_symbol: self._print_board() if turn % 2: self.p2.move(self.board) # replace this line with a call…
- User-defined Class: You will design and implement your own data class. The class will store data that has been read as user input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named MoneyChange. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 6 instance variables to represent amounts for each of the 6 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide a legitimate justification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriate get and set methods for…Focus on classes, objects, methods and good programming styleYour task is to create a BankAccount class.
