[Unsolved] ArrayList getting Players inside it.....

i am trying to figure out how to give the players inside the array-list their items I have two different Arraylists one called Attackers and one Call Defenders. Look in the code below for more information on what i am trying to accomplish. Thanks

Code:java

 if(Defend.contains(po.getName())){
                                Player Defending = (Player) Defend.iterator();
                                po.teleport(new Location(Bukkit.getWorld("world"), -100.5, 70.5, 241.5));
                                ItemStack bow = new ItemStack(Material.BOW);
                                Defending.getInventory().addItem(new ItemStack(bow));
                            } else {
                                Player Attacking = (Player) Attack.iterator();
                                po.teleport(new Location(Bukkit.getWorld("world"), -215.5, 64.5, 205.5));
                                ItemStack Pick2 = new ItemStack(Material.STONE_PICKAXE);
                                Pick2.addEnchantment(Enchantment.DIG_SPEED, 1);
                                Attacking.getInventory().addItem(new ItemStack(Pick2));
                                }

 

First of all, you may want to look into some java tutorials(especially with those variable names).
Second, what is po? What are you even doing? Calling .iterator() returns a new iterator made from the list, so you can't cast that to a player. Read javadocs, watch tutorials, and you'll know what you're doing wrong, but if you want help, we're going to need more of your code and whatever errors you're getting.
