HashMaps and teams...

Hey people of the bukkit community, I'm making a minigame plugin and I wanted to know how I would get the Object key size not the key size... Sorry if it don't really make sense

 

@DuskFireHD in a java.util.Map (guessing you are using a HashMap correct?) there is always one key for one object. so the amount of the maped objects is the same as the amount of the keys. also a map has the method size(). so you could just call map.size(); instead of map.keySet().size();

 

@Shmobi private HashMap<Player, TeamTypes> _team = new HashMap<Player, TeamTypes>();

I want a method like this also TeamTypes is Enum's

public int getSize(TeamTypes team){
if(team == TeamTypes.PLAYER){
return //I want to get how much is on that team..
}else if(team == TeamTypes.SPECTATOR){
return //Same here..
}
}

 

@DuskFireHD wait what? :O HashMap<Player, TeamTypes> would mean, that every player can only be once in the hashmap. and every player has one TeamType. i think what you are searching for is:
HashMap<TeamType, Set<UUID>> teams;
this would mean, that every teamtype has a set of uuid (players). so if you would do this:
Set<UUID> allSpectatingPlayers = teams.get(TeamType.SPECTATOR);
you would get a set of all players who are spectating. (use uuid instead of player. every player has a uuid which only exists one time. it is a primary key. use player.getUUID() )
if you use:
allSpectatingPlayers.size();
you know how many players are in the spectator team.

ps: remove the s of TeamTypes. enum-names should be singular
