java.util.ConcurrentModificationException on ArrayList

I am trying to remove items from a list inside a thread. I am getting the ConcurrentModificationException. I read from this link that it’s related to removing items from list. I am putting the sample code below. How can I do this properly without this exception in my case.

try 
{
    for(Game game:appDeleg.getGlobalGames().getGames())
    {
        if(game.getOwner().getId().equals(params[0]))
        {
            synchronized (appDeleg.getGlobalGames().getGames())
            {
                appDeleg.getGlobalGames().getGames().remove(game);
            }
        }

    }
}

catch (Exception e) 
{
    e.printStackTrace();
    return "noconnection";
}

Answer 1

use Iterator:

Iterator<Game> i = appDeleg.getGlobalGames().getGames().iterator();

Game game;
while(i.hasNext()) {
    game = i.next();
    if(game.getOwner().getId().equals(params[0]))
          i.remove();
    }
}
