Answer 16

You are creating a bowling game!
The given code declares a Bowling class with its constructor and addPlayer() method.
Each player of the game has a name and points, and are stored in the players HashMap.
The code in main takes 3 players data as input and adds them to the game.
You need to add a getWinner() method to the class, which calculates and outputs the name of the player with the maximum points.

Sample Input:
Dave 42
Amy 103
Rob 64

Sample Output:
Amy
