I can not figure out what to do for this question. I'm honestly lost and don't where to start.

I attempted the code but I'm clearly not getting it right.

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 (isTile) {
     tiles +- tile; 
    } else {
      != tiles +- tile;
    }
    return false;
  }

}

This is a tough challenge. I had trouble with this one too because I was also trying to use an if/else statement. But the code challenge has an easier solution in mind.

In the video before the challenge Craig talks about using the indexOf method in order to return the index of a letter in the hangman answer. 

indexOf('e') != -1;

In this case, the indexOf method is going to check the letter 'e' against the answer. If the letter 'e' is present then the index will be greater than -1.

For the hasTile method in the code challenge, you want to check against the tiles to see if the tile is present. If the tile's index is greater than -1, then the tile is present – and returns true. 

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