The UML must be complete and accurate. This includes classes, fields, constructors, methods $($including

parameters$),$ visibilities, relationships between classes, etc.

For this week, design the Tax Code example from this week$$s presentation. The UML should look similar

to your Singleton Wrapper that is generated from your assignment.

Things to look out for in UML:

$$ The wrapper$$s name should end in the word Wrapper in its name, as in $\_\_\_$Wrapper.

$$ The singleton should have a getInstance$()$ method.

$$ The singleton should have a private constructor

$$ The wrapper should be the only class in the UML to have a connection to the class that is being

wrapped.

$$ The wrapper should have methods for each behavior of the wrapped class that is being used.
