Use a target player from a command to a Listener?

Hey Bukkit community! I'm making a plugin where if you type /stats [Player] a InventoryGUI will pop up showing the players stats, like faction info. I've gotten the target player from when someone types "/stats [Player]" but then how would I grab stuff from the target player in a Listener? Here's my code:

Code:

            if (cmd.getName().equalsIgnoreCase("stats") && args.length == 1) {
                if (p.getServer().getPlayer(args[0]) != null) {
                    Player target = getServer().getPlayer(args[0]);
                    p.openInventory(inventory);

                }
                else {
                    p.sendMessage("Player is not available!");
                }
            } else {
                sender.sendMessage("You're not a player");
            }

            return true;
        } return true;
    }
    @EventHandler
    public void onOpen(InventoryOpenEvent e) {
        if (((e.getPlayer() instanceof Player)) && (e.getInventory().equals(inventory))) {
            Player p = (Player) e.getPlayer();
        }
    }

You can see I've put:

Code:

Player target = getServer().getPlayer(args[0]);

What would I do if I wanted to get stuff from that player and use it on the Inventory GUI, how would I do that? Sorry if I'm not being clear enough.

 

Store the player and the target player in a HashMap when opening the gui and remove it when closing it

 

Sorry, I'm still learning java itself, and don't know too much, how would I go around doing that?
and thanks for the reply.

Thanks but I can't use hashmap.add?

EDIT: Nevermind, thanks I think I did it.

 

That's why spoonfeeding is bad. Especially when it is completely wrong:
HashMap<K, V> not HashMap<T>
And the method is: .put(key, value);
