threats. We will simulate how the people seek to evacuate the building to safety, and how the threats spread throughout the building. Various events will be announced, such as person movements, threats spawning, and people reaching safety or succumbing to the threats. We will read a map representation from a file, and we will write the messages to either a file or just System.out as directed. In implementing this project, you will gain experience with a couple of new features, such as enumerations (both simple and complex) and interfaces. This will be a significantly larger project than we've had before! Hopefully you begin to see how larger programs truly need the mechanisms we've been learning in order to scale up successfully. One quick note - parts of the manual inspection criteria ("Coding Style and Readability") involve writing proper JavaDoc comments for classes/enums/interfaces, as well as for their members. You might as well do that from the beginning, and save yourself some valuable time at the end of the project.
