Programming Assignment 7

1 Purpose

The primary purpose of this assignment is to help you review (and demonstrate that you have acquired) the knowledge and skills required to create a program that uses described dynamic visual content.

2 Background

The (fictitious) company EnhancedRealty has now asked you to modify/extend the applet/application called HomeBase so that it displays both current property listings and an animation that shows the changing urbanization over time.

3 Documents

EnhancedRealty uses a heavyweight process (as opposed to an agile process) so they have created a fairly detailed set of specifications. They are described in the following document:

Specifications for the DynamicMapApplication

The data describing the urbanized area (over time) are contained in the following files:

urban-0.map
urban-1500.map
urban-4000.map

4 Submission

There is a two part submission process for this assignment.

You must submit (using Gradescope) a .zip file containing all of the code necessary to build your application. Gradescope will only be checking to ensure that your code complies with the course style guide. Hence, you may only submit to Gradescope five times. If you can't get your code to comply with the course style guide within five submissions, you will receive a grade of 0 on the assignment.
You must also submit (using Canvas) an executable .jar file named DynamicMapApplication.jar (that must NOT contain any of the classes in multimedia2.jar ).

5 Grading

You will receive one of four grades on this assignment -- 100, 75, 50, or 0. You will receive a grade of 100 if your code is essentially correct (i.e., a limited number of system tests do not cause any failures). You will receive a grade of 75 if you appear to have devoted significant effort to the assignment but your code has small defects. You will receive a grade of 50 if you devoted a reasonable amount of effort to the assignment but your code has major defects. You will receive a grade of 0 otherwise and/or if the code you submit to Gradescope code contains any style defects.

Gradescope will assign a maximum grade of 25 (based solely on style). Points will then be awarded manually based on the criteria discussed in the previous paragraph.

6 Help

You might find the following tips/hints helpful.

6.1 Approach

It's clear from the UML class diagram that the Visualization should now be a Stage. What's less obvious is that you should use a DescribedSprite and key-time animation for the "storm track" that consists of three different AggregateContent objects, one for each key time.

6.2 Code Duplication

Don't worry about code duplication across the StaticPropertyMap and DynamicPropertyMap classes. There are ways to avoid it, but it's not necessary to do so for this assignment.
