Because the computation takes time, it is better to first prompt a waiting message, which was not yet provided, to inform the user. However, the Service class is also used by other internal classes that do not need the message. Therefore, your job is to come out a way to provide the message without modifying the association relationship and the code of the Service class. What design pattern is a useful choice? Also,Show the new design in UML class diagram. Extra interfaces or classes can be added.
