Calling an object from another object

Okay, I'm trying to streamline my different ores by making a parent class called ore with all the common functions. I'm testing it using my copper class so I can revert it back if things don't go well. How can I call two+ different classes from the same function in the parent class of ore? If any of that did not make any sense, I apologize. If you need clarification feel free to ask, I'd be more than happy to further explain. Ore

                oreDisp = String.format("%.02f",(ore/1000)) + "k";

You do not "call a class", so it is not clear as to what you are actually asking. Specifics usually help in clarifying what is wanted.

Basically, I'm trying to pass the child as an object variable to the parent without having to write new code for each ore because there will be 6 in total. iron.getX() and all subsiquent references to iron are supposed to be oreType2, not iron. That was old code.

The class/subclass relationship is not a parent/child relationship. The word "extends" means exactly that -- a class becomes an extension of another class. Any object of any subclass of World is still a World object, regardless of which subclass it is created from.

"Basically" will not cut it. Be specific. What exactly are you trying to accomplish? Explain what you have, where you have it and the purpose for having it. Show codes. Details will make things go a whole lot quicker. I really think that you under some kind of misconception here and maybe the correct code, when given, will help clear things up a bit.

Idk maybe I'm just stupid but I don't think that made sense From what I understand you're trying to pass a reference of a subclass instance to the main clasgs? U can do that by using World.getObjects(classname.class)

I figured out an easier way to do it. I eliminated the Iron and Copper subclasses of Ore and just made the original call: 
addObject(new Ore('iron'), Greenfoot.getRandomNumber(1180), Greenfoot.getRandomNumber(550)+50);
addObject(new Ore('copper'), Greenfoot.getRandomNumber(1180), Greenfoot.getRandomNumber(550)+50);
Instead of 
addObject(new Iron(), Greenfoot.getRandomNumber(1180), Greenfoot.getRandomNumber(550)+50);
addObject(new Copper(), Greenfoot.getRandomNumber(1180), Greenfoot.getRandomNumber(550)+50);
And now it differentiates without having to have separate subclasses for each.

You can probably keep the Ore class and subclass it with the Iron and Copper classes. Common methods and fields can be placed in the Ore class instead of the subclasses. You should not run into problems in doing so. Anything specific to a particular type of ore should go in its specific class. Not saying you should go that route -- just saying that you should not have had issues in doing so.

The only thing that was different was coloring and name and what inventory slot it goes into. It was causing me to have to write multiple versions of the same function in the player.class, aka Mine(Iron iron), Mine(Copper copper), etc etc. This way I only have one class to pass. The only issue now is I fudged something up and even when I pass "Copper" to the Ore Class upon creation, it comes out looking like Iron, but being called Copper and when I mine it, it's count changes but doesn't add to Inventory. On the flip side, Iron is fine except that when I mine Iron I get both Iron AND copper in my inventory. Ore.class

EDIT: Figured out why it was adding to both Copper and Iron, I copied and pasted code and didn't change the second "Iron" to "Copper"

In the Ore constructors, you create new color variables instead of using the fields you already have. Remove all instances of "Color" at the beginning of these lines.

You should not compare possible like String objects using conditional comparison operators, like '=='. With objects, '==' means "is the same object as", not "is equivalent to". Better would be to use the 'equals' comparison method: 
if ("Iron".equals(oreObj.oreType))
Always put the new String object (a string in quotes IS a new String object) first when possible as you cannot call a method on a 'null' value (in case the referenced String has a 'null' value). In your case it probably does not matter; but, it is a good practice to be in the habit of doing.

I did that and now it's throwing up a "cannot find symbol - variable color1" error. Thanks again for all your help too danpost. You're always a big help.

Well the error is already telling u whats wrong, the compiler cant find your "color1" variable. Either you misspelled one of its uses or its not visible where u call it. If u're changing code inbetween errors provide us with the new one atleast tho >.< By the way, your first case in the ore constructor is unnecessary since your colors already have these values initially

Actually, there are two sets of colors -- one for iron and one for copper, which need to be set depending on the ore. The assignments in the field declaration lines can be removed. These colors can be set by the constructors of the subclasses (but the fields should remain in the Ore class). If not using subclasses, make sure you set the field values while not creating local variables with the same name.
