Solved Brackets In Player Names

Sorry if the title is confusing, but I created a plugin that when a player joins it does a basic MOTD, and also tells them the names of the online ops. But, for some reason, when I loops through all online players, check if any of them are ops, I get the list of them, but they have brackets (http://gyazo.com/8bcb21dc5dbe9bfad8205e8dba27697a) around the list. Is there any way I can remove this? I have tried everything that I know to get rid of them, but I couldn't.
PlayerJoin class:

Code:

List<String> ops = new ArrayList<String>();
        for (Player p : Bukkit.getOnlinePlayers()) {
            if (p.isOp()) {
                String pName = p.getName();
                ops.add(pName + ", ");
            }

Any help would be appreciated.

 

Why are you calling the toString() method on the player's name when it's already a string..

And you're not even showing the PlayerJoinEvent code.

 

Looks like you are treating the list as a string. You could do something like this...

Code:

String list = "Online Operators: ";
for (String s : ops)
{
    list = list + s + " ";
}

and then display the String list.

 

@SuperOriginal Sorry, I don't know why that extra .toString() was there. Must have been an accident. I'm also not showing the full class because it's a big class. I just thought I'd post the relevant code.

@WiseHollow I'm treating the list as a string because player names are technically strings. Plus, that was the best way I could do this.

There's no "technicality" about it, player's names are Strings. A List<String>, however, is not.

Use a StringBuilder, not a List, as a List is not meant for what you're trying to do.

 

@mythbusterma I must admit, I have never used a StringBuilder before. Could you give me some sample code?

 

@CodePlaysMinecraft http://docs.oracle.com/javase/7/docs/api/java/lang/StringBuilder.html One of the best sample codes there are!

 

@teej107 Lol, thank you. I looked over it a bit and this is what I got out of it:

Code:

StringBuilder sb = new StringBuilder();
        for (Player p : Bukkit.getOnlinePlayers()) {
            if (p.isOp()) {
                String pName = p.getName();
                StringBuilder onlineOps = sb.append(pName + ", ");
            }

However, when I try to use it in a line of code like "player.sendMessage("Online Staff: " + onlineOps);" I get this error message under onlineOps, "onlineOps cannot be resolved to a variable."

Problem solved! Thank you everyone for replying! For future people having the same (or similar) problem here is the code that I used to solve the problem:

Code:

StringBuilder onlineOps = new StringBuilder();
        for (Player p : Bukkit.getOnlinePlayers()) {
            if (p.isOp()) {
                String pName = p.getName();
                onlineOps.append(pName + ", ");
            }
player.sendMessage(ChatColor.WHITE + "Online Staff: "
                    + ChatColor.AQUA + onlineOps);
