You have to get key of max value so just print key, don't add in keys.

public void getWinner(){
int max = Collections.max(players.values());
for (Map.Entry<String, Integer> entry : players.entrySet()) { // Iterate through the map
if (entry.getValue() == max) {
System.out.println(entry.getKey()); // Print the key with max value
break;
}
}
}

Answer 2

The description is in the code below

import java.util.*;
import java.util.Map.*;

public class Bowling {
HashMap<String, Integer> players;
Bowling() {
players = new HashMap<String, Integer>();
}
public void addPlayer(String name, int p) {
players.put(name, p);
}
//your code goes here
public void getWinner() {
//takes the max number from HashMap values
int maxValueinMap = (Collections.max(players.values()));
//Loops through the HashMap to find the number
for (Entry<String, Integer> entry : players.entrySet()) {
if (entry.getValue().equals(maxValueinMap)) {
//prints out the key from the max value
System.out.println(entry.getKey());
}
}
}
}

public class Program {
public static void main(String[ ] args) {
Bowling game = new Bowling();
Scanner sc = new Scanner(System.in);

for(int i=0;i<3;i++) {
String input = sc.nextLine();
String[] values = input.split(" ");
String name = values[0];
int points = Integer.parseInt(values[1]);
game.addPlayer(name, points);
}
game.getWinner();
}
}
