OOP, Class Hierarchies and Interfaces.
4. Create three abstract classes Fresh, Soft and Firm that extends Cheese
These classes have:
- A protected constructor with three parameters: name, type, and fat percentage.
5. Create the Mozzarella, Brie, Parmesan and Cheddar classes
Class Mozzarella extends Fresh, Brie extends Soft and Parmesan and Cheddar extend Firm all have:
- A constructor with two parameters: name, and fatPercentage. Be sure to set the CheeseType correctly.
- A constructor with one parameter: name. This constructor should set the fatPercentage to a random value between 5% and 60%. Be sure to set the CheeseType correctly.
6. Create the ManoaCheeseFromager class
Create a ManoaCheeseFromager singleton class that can create Mozzarella, Brie, Parmesan and Cheddar Cheeses. Singleton classes have a static method getInstance() that returns the one and only one instance of the class. The class must implement the CheeseFromager interface.
Heres a screen shot of my ManoaCheeseFromager class.
Notice there are no Problems in my project. That means that there are no compile or checkstyle errors.
Implement the CheeseFromager methods. The makeCheese method should check the CheeseType then bake a random Cheese of that type.
At this point you can test your code with ManoaCheeseFromagerTest.java. We are going to use the JUnit tests to evaluate your homework for correctness.
7. (Optional) Create some Comparators
Next weeks homework is sorting an array of Cheese. You will need to create two comparators to do the sorting, so you can get a head start on next weeks homework by:
-
Creating a FatComparator that implements Comparator deciding based upon the Cheeses fat percentage values.
-
Creating an TypeComparator that implements Comparator deciding based upon the type of the Cheeses.
You can test your comparators using CheeseComparatorTest.java.
