I don't know what I am doing wrong

Correct the existing hasTile method to return true if the tile is in the tiles field, and false if it isn't. You can solve this a few ways, however, I'd like you to practice returning the result of the expression that uses the index of a char in a String.

After I run it I keep getting the message: Bummer: While you could definitely solve this using an if statement, try returning the result of the expression.

I don't know what exactly to do

public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;

  public ScrabblePlayer() {
    tiles = "";

  public String getTiles() {
    return tiles;

  public void addTile(char tile) {
    // TODO: Add the tile to tiles
    tiles += tile; 


  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    int result = tiles.indexOf(tile); 

      return true; 
      return false;

There is no need to store the result of answer of indexOf() and then check it with an if statement.

Instead just directly check if indexOf() returns -1. So, like this:

return tiles.indexOf(tile) != -1

They just want you to get used to the fact that if you check the result of indexOf() against -1, you already have the result you need.
