/**

public class Cart {
  
// Item Number
private int _itemNumber;
// The items
private List<Food> _itemsFood = new ArrayList<Food>();
private List <Food.FoodSize> _itemsFoodSize = new ArrayList<Food.FoodSize>();

}
// remove
//method to remove
public void removeItems(Food item, Food.FoodSize size){
