C.
Class that defines various static methods to create and calculate the costs of meals and orders.
a.
b.
Return an array of Menu arrays representing the order.
The largest meal should occupy index 0 in the returned array. Subsequent meals in the array
should have one less item than the meal at the previous index
d. Each meal in the order should be populated with Menu items such that each kind of Menu has an
equal chance of being selected
C.
Takes an int representing the length of the mean. (using java.util.Random)
Return a Menu array of the specified length representing the meal.
Populate each slot in the Menu array such that each kind of Menu has an equal chance of being
selected.
mealCost
a.
b.
Takes in an int representing the number of means in the order. (this parameter also represents the
length of the largest meal.)
C.
Takes in a Menu array representing the meal of which to calculate the cost.
Return an int representing the cost of the meal.
orderCost
Calculate the cost of the meal. (The price of the given Menu element is calculated as the product
of its index in the meal and the index of that Menu as it was enumerated in the Menu enum.
Takes in an array of Menu arrays representing the order of which to calculate the cost.
Return an int representing the cost of the order.
The cost of the order is the sum of the costs of each meal in the order.
