Java Java Objects Creating the MVP Scrabble Tiles

After multiple tries... It may well be right in front of my eyes though I can't quite see it!

Thank you.

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
   return false;
  }

   }

}

Hi Miguel,

In the hasTile method, use the indexOf() method on the tiles array and see if tile has an index greater than or equal to zero. Return that comparison from the method. So, tiles.indexOf(tile) returns zero or more if tile is within tiles. Make that test >= 0 and return the result from the method.

Let me know how you get on.

Steve.

Hi Steve,

I tried this:

public boolean hasTile(char tile) {
boolean hasTile = tiles.indexOf(tile) >= 0; 
return true;
}

It tells: I checked hasTile('z') and it returned true, but it isn't actually in the tiles. I verified with player.getTiles().indexOf('z') == -1.

Instead of assigning the result of that expression to a boolean variable, just return its result.

You mean:

hasTile = tiles.indexOf(tile) >= 0;

(?)

Try return tiles.indexOf(tile) >= 0;

Yep. It worked! I often tend to think it's harder than it really is. I just took up and I'm aware this is gonna be TOUGH. Gotta hang in there, though!

Thanks you, Steve! Much appreciated.
