Store.java
This will be the class that stores the data for the dessert store. We are assuming that a store can sell all kinds of dessert.
Variables:
-
String name – name of the store.
-
ArrayList desserts – an ArrayList of type Dessert
Constructor(s):
• A constructor that only takes in name and creates an empty ArrayList of type Dessert. Methods:
• addDessert
o This method should take in a valid Dessert object and add it to the back of the ArrayList. o This method should not return anything.
o This method should run in O(1) time.
• removeDessert
o This method should take in a valid Dessert object and remove the first instance of it from the ArrayList.
o Return the object that is being removed or null if the dessert is not found.
o Use equals when identifying if the object in the ArrayList is the same as the passed in Dessert object.
o This method should run in O(n) time.
• findDessert
o This method should take in a valid Dessert object and find/return the dessert that has the same sweetness and flavor.
o If a dessert with the same sweetness and flavor is not found in the Store, return null. o This method should run in O(log n) time.
o Assume the ArrayList has unique dessert items and is sorted in ascending order based
on sweetness and flavor.
• sortStore
o This method should sort the ArrayList in ascending order based on sweetness and
flavor.
o This method should run in O(n2) time worst and best case.
• checkStore
o This method should take in a valid Dessert object and return the number of desserts in
the store that is greater or equal to the Dessert passed in. o This method should run in O(n) time.
• If necessary, add getters and setters for the variables in the class.
