Get all players in an event

Does anyone know how to get all the players in a PlayerJoinEvent I think you need a list but can anyone guide me through that process thanks

 

well a player join event is just one player at a time, but you can use Bukkit.getOnlinePlayers() to return a list of all online players when someone joins?

 

Yeah but what Im trying to do is check once all the total number of players in game is = to 4
List<Player> allplayers;
int countplayers = allplayers.size();
if (countplayers == 4){
for (int swag = 0; swag == countplayers; swag++){// error the type of expression must be an array type but is resolved to a list<Player>
Player hi = allplayers[swag]; // error the method counter(PlayerJoinEvent) in the type castlewars is not applicable for the arguments player
counter(hi);
}
}

 

i'm not 100% sure what you're trying to accomplish.. but there are a lot of things wrng with your code. Only one i'm going to make sure to mention here is NEVER store a player object, always store the name. You'll pre-emptively stop 9 million problems that way

Code:java

List<String> playerNames = new ArrayList<>();
@Override
public void onEnable(){
//all your enabel stuff
}
@EventHandler
public void playerJoin(PlayerJoinEvent e){
Player p = e.getPlayer();
playerNames.add(p.getName());
if (playerNames.size >= 4){
//not sure what your are trying to do with this next part
for (String name : playerNames){
Bukkit.getPlayer(name).sendMessage("hi?");
}
}

 

Thanks fairly new to coding in general appreciate your help
