HashMap comparing second values?

Hey I am making a team plugin and I normally use Arrays for the teams, but I noticed HashMaps would be nicer as I only would need 1 HashMap for all teams, though now I am stuck on a autobalance funtion.

Code:

    private HashMap<Player, String> players = new HashMap<Player, String>();
 
    public void divideTeams() {
        for (Player player : players.keySet()) {
            ??
            }
    }

The strings should be "red" and "blue" and I would like it to check the amount of players that have the string set red and the amount of players that have the string set to blue. Then while going through always giving the next person the string that has less ppl assigned.

Thats the way I did it with Arrays:

Code:

for (Player player : players) {
                    int blue = blueTeam.size();
                    int red = redTeam.size();
                    if (blue >= red) {
                        redTeam.add(player);
                    }
                    else if (red > blue) {
                        blueTeam.add(player);
                    }

 

Using two lists or sets is probably better than using a map in this situation. Just because you can use a single map doesn't mean you should, sometimes other options are better.

 

Code:

int red = 0;
 
int blue = 0;
 
for(String team: players.Values()){
 
        if(team.equals("red")){
                    red++;
        }
        if(team.equals("blue")){
                    blue++;
        }
}
if (blue >= red) {
        players.add(player, "red");
} else if (red > blue) {
        players.add(player, "blue");
}
