Answer 1

Set.toArray() returns Object[]
but you can specifi return type in parameter

String[] keys = players.keySet()
//.toArray();
.toArray(new String [0]);

return in getWinner is inside for()
//return largestName;
}
return largestName;

getWinner() not need parameter, can access HashMap inside Bowling object.

//public String getWinner(HashMap players) {
public String getWinner() {

Answer 2

Your getWiner() method currently needs a raw HashMap.
You should remove it so it uses the instance variable players instead and then add a return statement to line 23 if there are no winners.
