please answer with proper explanation and step by step solution. Question: Program in python: Design a simple class called Dealership, that has two functions: buyCar(Car a) and sellCar(Car a). buyCar(Car a): Adds the car to the list of cars already in the dealership. sellCar(Car a): Removes the car from the list of cars already in the dealership. Note: Implementation of the Car class is not important for this question

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…
- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True False
