I´ve got this code:

import java.util.HashMap;


public class Main {
    public static void main(String[] args) {


        HashMap<String, String> mapAtletas = new HashMap<>();


        mapAtletas.put("Lionel Messi","Futebol,130");
        mapAtletas.put("Lebron James","Basquete,121");
        mapAtletas.put("Cristiano Ronaldo","Futebol,115");
        mapAtletas.put("Neymar","Futebol,95");
        mapAtletas.put("Stephen Curry","Basquete,92");
        mapAtletas.put("Kevin Durant","Basquete,92");
        mapAtletas.put("Roger Federer","Tênis,90");
        mapAtletas.put("Canelo Álvarez","Boxe,90");
        mapAtletas.put("Tom Brady","Futebol Americano,83");
        mapAtletas.put("Giannis Antetokounmpo","Basquete,80");




        mapAtletas.forEach((key, value) -> System.out.println(key + ":" + value));
        //Calculate the average by sport


        //Show the highest sport average

    }
}

How do I do this? Any clue?

I´ve tried to do a split() first to put in array. But how do I get the second value of this array gebnerated?
