Explain the difference between the protected and public members of a class.
In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract.   Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example:  Triangle, Area: 7.5, Perimeter: 12.0   Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: #   Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: #   Write a TestShape class that has the main method, which creates…
Subtask I: You will implement two classes Bid and Auction. The details are as follows: To keep things simple, each bid contains 3 attributes: bid_id: the identifer for this bid; • bidder_id: the identifer of this bidder; and auction: the identifer of this auction. ● Notice that bid_id is a unique identifier (think of a ticket) used to identify a bid whereas bidder_id identifies the person who made this made. Details about your Bid class: Your Bid class • can be instantiated via Bid (bid_id, bidder_id, auction), for example, bidtest = Bid(1, '8dac2b', 'ewmzr') provides the following access to data: If b is a Bid instance, then b. bid_id, b. bidder_id, and b. auction store this bid's bid_id, bidder_id, and auction, respectively. • has appropriate __str__ and __repr__ methods that show this bid's information. We do not specify the format. supports comparison using , ,==: two bids are compared exclusively by their bid_id. As an example, a bid with bid_id 3 is (strictly) smaller than a bid…
