Explanation

The players are first sorted descending by score, then ascending by name.

class Checker implements Comparator<Player> {

    // complete this method

    public int compare(Player a, Player b) {

        if(a.score>b.score) return -1;

        else if(a.score<b.score) return 1;

        else return a.name.compareTo(b.name);

    

    }

}

public class Solution {

    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);

        int n = scan.nextInt();

        Player[] player = new Player[n];

        Checker checker = new Checker();

        

        for(int i = 0; i < n; i++){

            player[i] = new Player(scan.next(), scan.nextInt());

        }

        scan.close();

        Arrays.sort(player, checker);

        for(int i = 0; i < player.length; i++){

            System.out.printf("%s %s\n", player[i].name, player[i].score);

        }

    }

}
