o Create 4 types of rental cars
o Toyota Corolla, 4
o Dodge Minivan, 7
o Ford Escape Hybrid, 5
o Yamaha Motorcycle, 1
o Create a RentalCarFactory class that takes number of people as a parameter and returns the smallest car that will fit everyone
o Write a Test class that does the following in its main()
Extra Credit
o Use the observer pattern to support a mythical broadcast system
o Create a Broadcaster class that supports:
o void register (Receiver r) – objects of type Receiver can register
o void broadcast (String message) – sneds message to all registered Receivers
o The Receiver class should support:
o Receiver(String name) – constructor that sets the name
o void receive (String message) – accepts messages sent to it and prints them out
o Write a Test class that does the following in its main()
This should result in the output below
