Refer to the following for Questions 37 and 38.
A word creation game uses a set of small letter tiles, all of which are initially in a tile bag. A partial implementation of a TileBag class is shown below.
public class TileBag {
//tiles contains all the tiles in the bag private List<Tile> tiles;
//size is the number of not-yet-used tiles private int size;
//Constructors and other methods are not shown. }
Consider the following method in the TileBag class that allows a player to get a new tile from the TileBag.
public Tile getNewTile() {
if (size == 0) //no tiles left return null;
int index = (int) (Math.random() ∗ size); size--;
Tile temp = tiles.get(index);
/∗ code to swap tile at position size with tile at position index ∗ / return temp;
