A Personal Address Book application program allows the user to add, delete, search, save, and load contact information. The program separates the user interface (command-line) and the internal processing subsystem. The internal processing system consists of the following classes: • • Contact Manager (responsible for add and delete operations) Contact Finder (responsible for the search operation) pataManager (responsible for save and load operations) a. What design pattern can be used to implement the user interface? Explain your answer using a class diagram for the entire system. b. Draw a UML sequence diagram to show the behavioral view of the Personal Address Book program, demonstrating what happens when a user enters new contact information.
