. A complex number is a number which can be put in the form a + bi. Create a class for complex numbers, which handle real and imaginary part separately. Class should consist minimum required constructors, get and show methods also Overload the + operator for this class which work like this formula. (a + bi) + (c + di) = (a+ c) + (b+ d)i.

- Create a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…· 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 Saving balance = Checking…Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle.

- This is for my python class, so python code please. This code needs to take inputs from a outside source/program, not for specific examples. Sorry for the confusion. 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt5. Given the Java Point class (which contains two private variables x and y and constructors that allows creating a point object with known x and y values as well as other methods such as equals( ), toString( ) etc), (a). define a new class called Circle that contains private two variables: center which is a Point object from the Point class and radius which is of type double. The Circle class must have the following methods: (b). add a constructor which creates a circle object using a center point with x and y values and a radius as its parameters. (c). add a default constructor. ( (d). add an equals() method that can compare if any object is equal to a Circle object (two circle objects are equal if they have the same center point with the same radius). (e). add a toString() method that prints a Circle object with the center point and radius.16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)
- 1. Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. 2. Create array of countries called Arab of 22 countries, Write a function fill that fills the arrav Arab 3. Write a method that finds the city that has the max area in a country 4. Write a method that sorts the cities in a country from the largest to the smallest area 5. Write a function that retums array of countries of the same area of Arab 6. Write a function that compares between two countries. It returns true if countryl area greater than country2 area. 7. Write a function to move a city from one country to another.This is for python class, so please answer in python 9.12 LAB: Product class In main.py define the Product class that will manage product inventory.

Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…
