Give a player items from config

Hi i'm trying to load items from the config and then give it to the player when he logs in, but nothing happen.

Config:
Items:
- STONE x 1

String[] item = itemLore.get(i).split(" x ");

//item is giving me STONE(item[0]) and 1(item[1])

if(Material.getMaterial(item[0]) == null){
Bukkit.broadcastMessage(ChatColor.RED+"ITEM: "+ChatColor.GOLD+item[0]+ChatColor.RED+" was not Found!");
}else{

player.getInventory().addItem(new ItemStack(Material.valueOf(item[0]),Integer.parseInt(item[1])));
}

It's just saying null
