Hashmap issue

Okay so I've been working with HashMaps for a while and I think I understand them. What I'm trying to do is to check for all of the players to see if any of them are in the "ingame" hashmap, and if they are then the player joins the game but if they aren't then the player joins the lobby. Here's some of the code but it doesn't work:

Code:java

                if(player.getWorld().getName().equalsIgnoreCase("flatlands")){
                    for(Player all : Bukkit.getServer().getOnlinePlayers()){
                    if(ingame.containsKey(all.getName())){
                    }
                Bukkit.broadcastMessage(ChatColor.GREEN + "" + ChatColor.BOLD + player.getName() + " has joined the game!");
                    }
            }else{
                Bukkit.broadcastMessage(ChatColor.GREEN + "" + ChatColor.BOLD + player.getName() + " has joined the lobby!");
            }
                    }

Here's the code for the HashMap.

Code:java

        HashMap<String, Block> ingame = new HashMap<String,Block>();

And right now I have a code that puts the player into the hashmap for testing

Code:

                Player player = (Player) sender;
                if(args.length == 0){
                ingame.put(player.getName(), null);
                }
                if(args.length == 1){
                    Player targetPlayer = player.getServer().getPlayer(args[0]);
                    ingame.put(targetPlayer.getName(), null);
                }
            }

Can anybody help?

 

Sorry I am slightly confused by the context. What are you trying to achieve exactly? What is the ingame hashmap supposed to contain? As I assume it's not just players in the world as you already have that information

Why would it work??? You are opening a bracket then immediately closing it:

Code:java

if(ingame.containsKey(all.getName())){}

Also, you can't have an else statement against a for loop.

 

AoH_Ruthless ah, didn't notice that.

Basically I am trying to check all the players to see if any of them are in the hashmap.

I'll try to mess around with it a bit and see if it works

Ugh, I can't figure it out. I've tried HashMaps and ArrayLists now ;-;

Ah nevermind I fixed it! If anyone else runs into this problem just create a boolean and set it to true or false when you want to

I was trying to over complicate things.
