Where do I find this information?

I have been stuck on this for a week. I have rewatched the videos but I have no idea what they want from me.

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) {
    tiles+=tiles;
    // TODO: Add the tile to tiles

  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return false;
  }

}

there's an index of method on string that accepts a character (see http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#indexOf(int) ) or look at other people's answers on that task (eg https://teamtreehouse.com/community/i-cant-find-the-error-in-the-hastile-method has a good explanation)

Hi,there you are

Challange 1 of 2 :

Here you have to combine existing string with new one :) 

 public void addTile(char tile) {
    // TODO: Add the tile to tiles
    this.tiles += tile;

  }

Challange 2 os 2:

Here you have to use indexOf method :) -http://docs.oracle.com/javase/9/docs/api/java/lang/String.html#indexOf(int)

 public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return tiles.indexOf(tile) >= 0;
  }

Hi Donald, there will be some points at which information might seem missing. If you have an issue, chances are several hundred other users had the same one (unless it's a brand new or exotic course). For example, there are 4 pages of posts related to just that one challenge (see https://teamtreehouse.com/community/code-challenge:16142 ). Some of these will include answer code and high quality explanations. The treehouse forum is searchable and also google indexed, which assists tracking down someone with the same issue.
