΢΢΢G Exercise P12.12. Write a program that can be used to design a
suburban scene, with houses, streets, and cars. Users can add houses and
cars of various colors to a street. Write more specific requirements that
include a detailed description of the user interface. Then, discover
classes and methods, provide UML diagrams, and implement your
