In this question, we will model a simple ordering application for an ice cream store. In our cream

store, we will have the base ice cream class, which has two attributes $($flavor and price$)$ It also supports

two methods

$$ getDescription that prints out the flavor of the ice cream

$$ getCost that prints out cost of the ice cream

Our application supports the decoration of the base ice cream by adding extra toppings to the ice cream.

Suppose we have two toppings $($sprinkles and nuts$)$ now and will extend it for more toppings in the

future. Each decorator modifies the description or cost of the ice cream without changing the basic ice

cream class. After adding the toppings, the getDescription method should print out the flavor as well as

the topping information. The getPrice method should include the cost of toppings to the total price.

Part $1$: Provide a UML Class diagram showing essential classes, dependencies, attributes, and operations

in your design by following the design pattern you selected. If necessary, add a description to make sure

the diagram can be easily understood by another person while keeping it as short as possible.

Part $2$: Implement your application using Java or C$++.$ In your implementation, please provide an

executable demo that shows how two toppings are added and getDescription and getCost methods

work correctly.
