Not sure what we suppose to do, if my code works, tells me i could do it my way but wants the result of the expression

Question

Code works why cant i move on, what is missing.

ScrabblePlayer.java

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) 
  {
      boolean result = false;
          if(tiles.indexOf(tile) != -1)
              {
                  result = true;
              }
          else
              {
                  result = false;
              }
      return result;     
  }

}

Nothing is missing, pretty much the opposite, your solution is way more verbose than what is needed.

Expressions like the one you use in your if statement "tiles.indexOf(tile) != -1" returns a Boolean value on it's own, so instead of setting up an if statement where you check what it returns and then manually return either true or false you can just return the expression directly. Like this:

public boolean hasTile(char tile) 
{
    return tiles.indexOf(tile) != -1;
}

That will have the exact same result as your solution but only requires one line of code.
