UML Command pattern and Sate Pattern


Hi All,

I'm new to Patterns, I would really appreciate if any one can help me
out to solve the below problems?

- Thanks in advance. -Bob

1) Show how the command pattern could be applied in the Monopoly game
design. Include a class diagram and sequence diagrams for do, undo, and
redo.

2) Show how the state pattern would apply to the Property class in the
Monopoly design. What are the states of a Property? How do they change?
Show the class diagram for the Property class with the application of
the state pattern. Show a sequence diagram for one of the state changes.
