Thread: Method takes parent class as parameter, realized I can't enter it's subclass as a parameter

Ok so I'm working on making a simple text-based game, and I've got two methods - one that removes an item from the player's inventory, and another that works with breaking said item. The issue comes in in that any object of class Items can be removed from inventory via the method removeFromInventory. The method breakItem only works for CombatItems, however, which are a subclass of Items. Only they can break, as only they have durability. Im not sure what it is that I can do, but heres the code from both methods, if its any help in figuring out what to do.

    public void removeFromInventory(Items I)
    {
        if(Inventory.size() >= 0 && Inventory.indexOf(c) >= 0)
        {
            Inventory.remove(I);
        }
 
        else
        {
            System.out.println("That item isn't located in your inventory.");
        }
    }
 
    public void breakItem(CombatItem c)
    {
        if(c.getCurDurability() <= 0)
        {
            removeFromInventory(c);
        }
    }

I want to put CombatItems in as a parameter of the removeFromInventory method, but that only takes in Items as a parameter, which CombatItems are a subclass of.

Copy the full text of any error messages and paste it here.

Okay so, I just realized what I could've done and avoided all this trouble, which was just overloading the method. In any case, the error I got was "Incompatible types: CombatItem cannot be converted to Items"
