Project question: Using a TreeMap to sort like values

Hi,

I've been stuck on the last project question for the Soccer League Organiser. The requirement states that as an organizer planning teams, I should be able to view a report of a chosen team grouped by height, so that I can determine if teams are fair.

To me this reads as;

Select your team then show all the players on that team grouped by height.

E.G;

42" Players Player1 Player2

40" players Player 10 Player 11

I know I've probably got to use a TreeMap or Set like interface but just having trouble sorting the data by height. This is what I have so far;

Map<Integer, List<Player>> playerHeights = new TreeMap<>();
        // Now display the players on that team
        for (Player player : mTeams.getTeams().get(teamIndex).getPlayers())
        {
            List<Player> playerList = new ArrayList<>();
            playerHeights.put(player.getHeightInInches(), playerList);
        }


        // Now display the players depending on their height
        for (int i = 0; i < playerHeights.size(); i++)
        {
                System.out.println("Players that are: " + playerHeights.get(i) + "\"" + " tall");
                System.out.println("PLAYER: " + playerHeights.get(i) + " " + playerHeights.get(i));
                System.out.println("");

        } ```
