I have a subclass BetterBasket that inherits from a superclass Basket, which itself inherits from ArrayList<Product>. My method add in BetterBasket adds an item searched through the ArrayList and if there is an object of the same type then the values must be added to the already existing object (merge the quantity and price), and if not the object must be added into the ArrayList. This is my code but it won't work properly, as it will add the products as needed but will not merge the same products. So it doesn't use the else part of the code.
@Override
public boolean add(Product pr)
{
if (!this.contains(pr)){ //if array doesn't contain the item
super.add(pr); //adds item
} else { //add item quantity and price to existing item.
double x = pr.getPrice();
int q = pr.getQuantity();
for (int i=0; i < super.size(); i++) //loop through array
{
if (super.get(i).equals(pr)){ //if item is same as item within
//the array
int w = super.get(i).getQuantity();
double y = super.get(i).getPrice();
super.get(i).setQuantity(q + w);
super.get(i).setPrice(y + x);
}
}
}
return true;
}
Should I use this or super for the first if statement? Why is the else branch not being used?
