Filling empty slots in a players inventory

So im making a Kit Plugin for someone but I got Stuck!
When someone does /refill I want their inventoryslots that doesn't have MushRoom_Soup Bowls to get MushRoom_Soup Bowls...

So Far this is my /refill code:

Code:java

if(cmd.getName().equalsIgnoreCase("refill")){
            ItemStack[] inv = p.getInventory().getContents();
            boolean gotBowl = false;
            for (ItemStack slot : inv) {
                  if ((slot != null) && (slot.getType() == Material.BOWL))
                  {
                    gotBowl = true;
                    slot.setType(Material.MUSHROOM_SOUP);
                    ItemMeta slotMeta = slot.getItemMeta();
                    slotMeta.setDisplayName("§6[§b§lHoly§e§lSoup§6]");
                    slot.setItemMeta(slotMeta);
                  }
                }
                if (!gotBowl)
                {
                  p.sendMessage(prefix + "§cYou have no empty bowls!");
                }

 

I believe you'll need to add the new ItemStack to their inventory. I would recommend creating an ItemStack with the appropriate type and meta outside the loop, then just using a standard for loop to iterate from 0 to the inventory size and setting all slots to the ItemStack you created.

 

Try using a for loop like
For(int I=0; I<36; I++){
Add a itemstack to slot value of I
}
Hope I helped

 

Well, all you want is to try and replace all items in their inventory with mushroom soup, so just go

inv.clear();
inv.addItem(new ItemStack(Material.Mushroom_Soup);
inv.addItem(new ItemStack(Material.Mushroom_Soup);
inv.addItem(new ItemStack(Material.Mushroom_Soup);
inv.addItem(new ItemStack(Material.Mushroom_Soup);
etc...

But, if you wanted to replace all Bowls with mushroom soup, the easiest way to do it I can think of (as in easiest, like lazyest) would be to just do if (player.getInventory.getSlot(or however you get the slot).equals(Bowl)
player.getInventory.getSlot.set(MushroomSoup)

Also, dont be lazy and use the &4 and stuff codes. Use ChatColor.(COLOUR)! Makes your code look much more beatufil

What you're doing right now checks if the slot is an empty bowl, then changes it to a mushroom soup bowl if so. If you want to fill empty slots, you need to follow the suggestion of mine-care and then set the item at the index to a new item stack.
