I wrote my codes like this: public class OrderApp { public void main(String[] args) { FoodOrder foodOrder; } } public class Customer { private String name; public void chageCrditCard() { } } public class FoodOrder { Customer customer; private long orderNumber; public void addItem (MenuItem i) { } public double getTotalCost() { return 0.00; } } public class MenuItem { public String name; protected double price; public double getPrice() { return price; } } public class ComboMeal extends MenuItem { private double discount; public double getPrice() { return price; } public void addItem (MenuItem i) { } } I'm not sure If I did the relationship between classes and implement each one right. Also, how do I express multiplicities and specifiers in the codes? And finally, please review the whole thing. Subject: Java Programming

The method should print the shapes of each polygon that has an area greater than 500 and return their count. The method prototype is public static int find (Polygon [] list); Note: assume the array is already declared, populated with data in the main method and ready to be used.
