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

Java - Car Value (Classes)

The class definition for an Item is given in the image UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1:  Create a class based on the specification above. Reminder:  – means private and +  means public. Part 2:  a)Write a function/method called “addItem” that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price   The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise.   b)Write a function/method called “listItems” that takes: An array of items The number of items in the array The function must return a string containing the information on each item in the array.   c)Write a function called “pricelookup” that takes : An array of items The number of…
