    Default Abstract Help

    Hello,

    I have this code

    public class BulkFoodQ2 extends FoodV5
    {
    private double unitCost;

    public BulkFoodQ2(String brandIn, String productNameIn, String unitsIn, double unitCostIn)
    {
    super(brandIn, productNameIn, unitsIn);
    unitCost = unitCostIn;
    }

    public void setUnitCost(double unitCostIn)
    {
    unitCost = unitCostIn;
    }

    public double getUnitCost()
    {
    return unitCost;
    }

    public void setUnitCostToThisUnitCost(FoodV5 anotherFood)
    {
    double tempUnitCost = anotherFood.getUnitCost();
    setUnitCost(tempUnitCost);
    }

    public double findCost(double amount)
    {
    return amount * unitCost;
    }

    }

    The class FoodV5 is an abstract, class and I am not understanding how to test the method.

    I am trying to test the setUnitCostToThisUnitCost.

    I created this:

    public class TestBulkFoodQ2
    {
    public static void main(String[] args)
    {

    FoodV5[] food = new FoodV5[2];

    food[0] = new BulkFoodQ2("Grain", "White Man", "Rice", 10.00);
    food[1] = new BulkFoodQ2("Pasta", "Wheatie", "Noodles", 15.00);

    for (FoodV5 f : food)
    System.out.println(f.getBrand() + ", " + f.getProductName() + ", " + f.getUnits() + ", " + f.getUnitCost());

    food.setUnitCostToThisUnitCost(10.00);
    System.out.println(food);

    }

    }

    The first part but the method for setUnitCostToThisUnitCost does not work. Any help would be appreciated
