In this assignment, you will be writing a program to check the nutrition values of a meal for Old Country Buffet. Old Country Buffet offers the following type of food:

1. Bakery
2. Entree
3. Drink

Each food has a name and label. Bakery has an extra attribute pieces, and Drink has an extra attribute volume. The calories of each serving can be determined by the following table:

Calories

	L	M	S
Bakery	300/piece	200/piece	100/piece
Entree	400	300	200
Drink	3/ml	2/ml	0/ml

All of your classes should be defined in chapter9.nutrition package. You should also implement a class named Plate, which has the following methods:

1. addItem(FoodItem item)
2. display()
3. getTotalCalories()

Your implementation should work for PlateTest.java, and PlateTest should produce the following output(so you can figure out what to output in display method for each class):

Name:.Steak Label:.L Calories:400 Name:.Sprite Label:.L Calories:300 Volume:.100 Name:.Ice.Tea Label:.M Calories:160 Volume:.80 Name:.Bread Label:.L Calories:300 Pieces:.1 Name:.Croissant Label:.M Calories:400 Pieces:.2 Total:.1560

We were given this:

package chapter9.nutrition; /** * Do not make any changes to this class. * Make sure that you move the file to the appripriate folder. */

public abstract class FoodItem { protected String name; protected String label;

public FoodItem(String name, String label) { this.name = name; this.label = label; }

public String getName() { return name; }

public String getLabel() { return label; }

public void display() { System.out.println("Name: " + name); System.out.println("Label: " + label); System.out.println("Calories:" + getCalories()); }

public abstract int getCalories(); }

and this :

/** * Do not modify this file, otherwise * you will not pass the first testcase. */

import chapter9.nutrition.Plate; import chapter9.nutrition.FoodItem; import chapter9.nutrition.Drink; import chapter9.nutrition.Bakery; import chapter9.nutrition.Entree;

public class PlateTest {

public static void main(String[] args) { Plate plate = new Plate(); plate.addItem(new Entree("Steak", "L"));

plate.addItem(new Drink("Sprite", "L", 100));

plate.addItem(new Drink("Ice Tea", "M", 80));

plate.addItem(new Bakery("Bread", "L", 1));

plate.addItem(new Bakery("Croissant", "M", 2));

plate.display(); System.out.println("Total: " + plate.getTotalCalories()); } }
