    Default Creating a "repeator" method.

    Hey.


    I've been trying to figure out how to do this for a few hours now. I have this sort of code:
    new InventoryBuilder().add("Item").empty(8).add("Item");

    Now, if I would want, say 8 times item:
    new InventoryBuilder().add("Item", 8).empty(8).add("Item", 8);

    The issue with this is that I end up with a crap ton of methods, considering it might have up to 3 arguments. I figured I could do something like this:
    new InventoryBuilder().repeat(8, new Repeater() { add("Item") }).empty(8);

    But I have no idea how would I implement this

    I feel like I walked into the theater in the middle of a movie. Are we supposed to know what you're talking about? Could you give us a little more to work with? What's the objective? What's your definition of a repeater method and what it does?

    It's a inventory builder for a game. Its idea is to place items in a inventory. The inventory has 9 items per row, so in this case it would be:

    with this code:
    new InventoryBuilder().add("Item").empty(8).add("Item");
    Would "output":
    "Item" *empty* *empty* *empty* *empty* *empty* *empty* *empty* *empty* "Item"


    Now if I would want:

    "Item" "Item" "Item" "Item" "Item" "Item" "Item" "Item" "Item"

    I'd have to write
    new InventoryBuilder().add("Item", 9);
    (The second argument being how many times to repeat it)

    Now the issue is, it can take quite a few arguments, it ALWAYS takes the "Item" argument, but it might also take "name" "lore" and bunch more. Having to add that "repeat" argument to every single method would be a hell. I thought I could make a "Repeat" method, which would take two arguments: one as how many times to repeat it and the second being the "method" aka ".add" to repeat that many times.

    With PHP I could make:
    PHP Code:
    inventoryBuilder($item$name ""$lore ""$repeat 1
    But Java doesn't have anything like that as far as I know.

    Java has loops and collections that can be iterated each time through the loop to repeat similar tasks multiple times with varying parameters. I think it's just a change in mindset from how you used to do it, but I'm not sure.

    I figured out one solution after stopping for a minute and thinking. Having only two arguments. add(Item, ItemOptions). ItemOptions being a class which could be used as following:

    new InventoryBuilder("Item", new ItemOptions().name("item").lore("items lore").repeat(8));
