Remove player from a list.

So with this code i add a player to a list.

Code:

Map<UUID, String> players = new HashMap<UUID, String>();
//Game refers to another class.
game.players.put(p.getUniqueId(), arenaName);

Then with this code i remove the player from the list on death

Code:

for (Entry<UUID, String> entry : players.entrySet())
                   {
                       if(entry.getKey().equals(p.getUniqueId())){
                           players.remove(entry.getKey());
                       }

                   }

But when i run the start code it still takes the player even tho i removed it.
With some debugging i came to the conclusion it didnt take tke player out of the list.
What do I do?

 

@MinecraftMart If you are getting a ConcurrentModificationException use an iterator.
