Chapter 9, Problem 19E

Create tests for SalesItem that test whether the find-MostHelpfulComment method works as expected. Note that this method returns a Comment object. During your testing, you can use the Get button in the method result dialog to get the result object onto the object bench, which then allows you to make further method calls and add assertions for this object. This allows you to identify the comment object returned (e.g., by checking its author). You can also assert that the result is null or not null, depending on what you expect.

Add comments as appropriate. Be sure that your program output is neatly presented to the user.  Add documentation comments to your functions. You are going to change the class you created in Program7 so that it has a constructor and some properties. In your GeoPoint class make the following changes (note your variable, parameter and method names may be different. Adjust as needed.): Add a constructor __init__(self, lat=0, lon=0,description = ‘TBD’) that will initialize the class variables __lat ,__lon and the __description. Notice that the constructor will also default lat and lon to zero and description to ‘TBD’ if they are not provided. Change the SetPoint method so that instead of individual coordinates SetPoint(self, lat, lon) it takes a single sequence. Add a property: Point = property(GetPoint,SetPoint). Make sure GetPoint and SetPoint are the names you used for the get and set methods you already wrote for points. Add another property: Description = property(GetDescription,…
Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.
Please answer the question in the attachment. It is a past AP Computer Science frq question that has already been answered, but I would like to see another way to approach the problem.
