QUESTION 8: UML Provide a UML class diagram of the Proxy Design Pattern applied to the following prob- lem. A client has given you access to an OfflineProcessor class that they use to batch pro- cess their monthly financial information. This class is only used once a month but is currently instantiated every time they run their program which makes the program take a long time to open. They want you to fix this by using a virtual proxy to only instantiate the object on a particular day of the month.
