HashMap subMap ?

Hey Bukkit, i'm here having some difficulties, i'm trying to divide an HashMap of players into 2 teams(different hashmaps), i used this method using ArrayList's but in this case i need to use HashMap.

So i have these 3 HashMaps:

Code:java

    public static Map<Game, String> in_lobby = new HashMap<Game, String>();
    public static Map<Game, String> on_red = new HashMap<Game, String>();
    public static Map<Game, String> on_blue = new HashMap<Game, String>();

I want to divide the in_lobby HashMap into the red team and the blue team, i have this code, but subList's are only for ArrayList's, so how would i do it with the HashMap ?

Code:java

        if(in_lobby.size() > 0){
            on_red.putAll(in_lobby.subList(0, in_lobby.size() / 2 + in_lobby.size()%2));
            on_blue.putAll(in_lobby.subList(in_lobby.size() / 2 + in_lobby.size()%2, in_lobby.size()));
            in_lobby.clear();
        }

 

BugsyFTW Why not add them first to a list, divide that list in 2, and then add them to the hashmap they belong to?

 

Why not make Game contain a method called getTeam() that returns a team enum? Then you can loop through the map and check if the player is on red team or blue team.

 

This is before the game starts, it's shuffling and then diving the players into 2 even teams

 

BugsyFTW Just put all the players in a list, divide the list in 2, put one half in the on_red map and the other galf in the on_blue map.

 

Loop through and add every other player to one list and the rest to the other?

 

BugsyFTW Try this:

for(Player player : Bukkit.getOnlinePlayers()){
boolean b = false;

if(b){
//put in red
b = false;
}else{
//put in blue
b = true;
}
}
