RankGUI help

So I am coding a rank GUI for my server. I want to see if args[0] is an online player. If so I want to be able to reference it in the case statements below. Please help.

Code:

        Player player = (Player)sender;  
       

       
        Inventory RankGUI = Bukkit.createInventory(player, 45, ChatColor.BLUE + "Rank GUI");
           
            ItemStack Head = new ItemStack (Material.SKULL_ITEM);
            SkullMeta headMeta = (SkullMeta)Head.getItemMeta();

@ChucknorisSR Just check if Bukkit#getPlayer(args[0]) isn't null.

 

That still doesn't allow me to get the player so I can give them a rank with my methods.

 

@ChucknorisSR

Code:

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

if(target == null) {
  //Player is offline
} else {
  //Player is online, do whatever
}

 

I still need away to use the variable "target" down is my case statements. That is how I am giving the player the rank.

Bump still need responses!

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@ChucknorisSR this worked for me back when in the days:

Code:

Player p = Bukkit.getServer().getPlayer(args[0]);
if(p == null || !p.isOnline()) {
 return true;
}
