# (a) Create a class Dessert with getters and setters for name and calories. Define
# instance methods healthy?, which returns true if a dessert has less than 200
# calories, and delicious?, which returns true for all desserts.

# (b) Create a class JellyBean that extends Dessert, and add a getter and setter for
# flavor. Modify delicious? to return false if the flavor is black licorice (but delicious?
# should still return true for all other flavors and for all non-JellyBean desserts).
