Description
Exercise 1 (15 pts)
We have covered three design patterns in class (Strategy, Adapter, Observer). Pick two
design patterns (any two that you want –you can even do research on your own and
find another one you like!) and couple them.
Two design patterns are coupled when at least one class is a participant in both design
patterns.
a) Draw a UML class diagram that clearly shows the coupling. Please identify
which class(es) participates in multiple patterns.
b) Draw a UML Sequence diagram where you demonstrate the behavior of an
instance of the coupled class from the perspective of one pattern, then from the
perspective of the other pattern.
Exercise 2 (10 pts)
a) “Man in the Middle (MitM)” and “Cross-site scripting” are famous type of cyber
