Correct the hasTile method.

Hey Anders. I keep trying the problem, but I seem not to get it right for some reason. Can u tell me what is wrong with what I did on the second question?

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) {
    // TODO: Determine if user has the tile passed in
   if(tiles.indexOf(tile)!=-1){
   // if(hasTile!=-1){
         return true;}
    else{
         return false;}

  }

}

You're gonna like this one. He wants you to use only a one line expression, return the evaluation itself, without an if(). Try this, return tiles.indexOf(tile) >=0; This test will return a boolean. You could also try != -1 as you have there in your code, but use no 'if' 'else.' Just tell the method to return the boolean evaluation in one line. See "test operators."
