    my JS solution - with class

    function processData(input) {
  //Enter your code here

  const scores = [];

  const inputAr = input.split('\n');
  inputAr.shift();

  for (let score of inputAr) {
    scores.push(new Score(score.split(' ')));
  }

  scores.sort((a, b) => a.compare(b));

  const ranking = scores.map((score) => score.toString());

  console.log(ranking.join('\n'));
}

class Score {
  player = '';
  score = 0;

  constructor([player, score] = playerScore) {
    this.player = player;
    this.score = +score;
  }

  compare(playerB) {
    return this.score < playerB.score
      ? 0
      : this.score === playerB.score
      ? this.player.localeCompare(playerB.player)
      : -1;
  }

  toString() {
    return this.player + ' ' + this.score;
  }
}

    JS

    function processData(input) {
    //Enter your code here

    const data = input.split('\n');

    const arr = []

    for (let i = 1; i < data.length; i++) {
        const [name, scores] = data[i].split(' ');
        arr.push([name, scores])
    }


    const rr = obj.sort((a, b) => {
        if (b[1] !== a[1]) {
            return b[1] - a[1];
        }
        return a[0].localeCompare(b[0]);
    });

    const result = rr.map(r => r.join(' ')).join(' \n')

    console.log(result);

    if you are working on java 15.

    import java.io.; import java.util.;

    public class Solution { public static void main(String[] args) { Scanner sc=new Scanner(System.in); int n=sc.nextInt();

        checker[] arr=new checker[n];
    for(int i=0;i<n;i++){
        String name=sc.next();
        int no=sc.nextInt();
        arr[i]=new checker(name,no);
    }
    compare(arr);

    for(int i=0;i<arr.length;i++){
        System.out.println(arr[i].name +" "+ arr[i].no);
    }
}

public static void compare(checker[] arr){
    Arrays.sort(arr,(o1,o2) -> {
        int nocompar=Integer.compare(o2.no, o1.no);
        if(nocompar == 0){
            return o1.name.compareTo(o2.name);
        }
        return nocompar;
    });
}

    }

    class checker{ String name; int no;

    checker(String name,int no){
    this.name=name;
    this.no=no;
}

    }
