String name = values[0];
int points = Integer.parseInt(values[1]);
game.addPlayer(name, points);
0301
}
game.getWinner();

Answer 1

First of all, you putted "0301" in your code for no reason. Also you missed a curly bracket at the end. And finally you should use .equals() rather than == here

This code shall work:

Answer 2

Hi Aleksei, I haven't seen the "Map.Entry" in any of the lessons... or I assume I missed it. Do you happen to know where it is to read about?

Also, if one is using the Collections.max, why do you then need the "equals()" at all? I figured (again incorrectly it seems) that you could just output the Max value. Any thoughts there?
Thanks in advance!!
