1. Draw a UML diagram similar to the ones shown in this chapter for the following classes and interface and submit as a document.

-An abstract class called HotDrink that has the methods Drink, AddMilk, and AddSugar, and the properties Milk and Sugar

-An interface called ICup that has the methods Refill and Wash, and the properties Color and Volume

-A class called CupOfCoffee that derives from HotDrink, supports the ICup interface, and has the additional property of BeanType

-A class called CupOfTea that derives from HotDrink, supports the ICup interface, and has the additional property of LeafType

Write some code for a function that will accept either of the two cup objects in the preceding example as a parameter. The fucntion should call the AddMilk, Drink, and Wash methods for any cup object it is passed. Submit screenshots of code and results.

Create a WPF application that employs the .NET class System.Object to create a button object that affects the text of the button (polymorphism). You will also use the same application to make changes to a child object (button) using hierarchy. Submit screenshots of both versions of the application and their output.
