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.
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;
}
}

What it does: it takes char tile as a parameter and looks for it in the String tiles. IndexOf returns positive index number if your char was found in the String and negative if it wasn't. So basically we are saying here: as long as the index of tile char is not -1 (not found), then return is true.
public boolean hasTile(char tile) {
return tiles.indexOf(tile)!=-1;
}

Keep in mind most of the time there are dozens of existing treehouse forum posts for a given problem (eg.https://teamtreehouse.com/community/code-challenge:16142) . Sometimes it can be quicker than waiting for a new response.
