  1. So today I wanted to write a "simple" shop plugin but I ran into this hell of an exception and I don't know how to fix it.

    The line in question is:
    Code (Java):
    if (item_names.get(i).contains("/")) {
    The sorrounding code is following:
    Code (Java):
    for (int i = 0; i < ItemManager.items.get(name).size(); i++) {
                if (item_names.get(i).contains("/")) {
                    String[] split = item_names.get(i).split("/");
                    String[] split2 = items_pre.get(item_names.get(i)).split("/");

                    List<String> test = new ArrayList<String>();

                    test.add("§7§lPreis: §c" + split2[0]);
                    test.add("§7§lVerkaufen fuer: §c" + split2[1]);

                    ItemStack item = new ItemStack(Material.valueOf(split[0]), 1, Short.valueOf(split[1]));
                    ItemMeta item_m = item.getItemMeta();

                    inv.setItem(i, item);
    To explain this - so you can better undstand what I'm trying to do.

    I have an ItemManager which has a few lists in it (including item_names (ArrayList) and items_pre (HashMap))
    Every entry in item_names is just the name of the variable of the item in Material#
    Example: Entry in my list: IRON_INGOT
    Result in Material#: Material.IRON_INGOT
    items_pre are just the Items with the buy / sell values and metadatas as well as the Material# variable
    Example: Entry in my list: Key: STONE/1 <- the 1 being the metadata (in this case granite)
    Variable: 25(buy value)/15(sell value)
    In this case the list item_names has 17 Entrys.

    The Exception is following:
    Code (Text):

    If any questions about my code remain - please feel free to ask.
    Thanks for reading and I hope you can help me.
