Challenge Task 2 of 2

Okay great, now can you fix the hasTile method for me, right now it always returns false. 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.

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

}

Hi Manas,

Using an if statement can work. But you can return the expression in a much simpler way.

If you're returning an expression, you don't necessarily need an if statement since returning an evaluation.

Declare the method and then take the expression in your if statement and simply add it to your methods return keyword.

Good luck! :-)
