783 PointsI can't find the error in the hasTile method,
I need to return true if the char tile is in tiles string, and false if not. Can't find the mistake
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(tiles.indexOf(tile) <= -1) {
return false;
}
if(tiles.indexOf(tile) >= 0) {
return true;
}
}
}

Treehouse TeacherHi there! You have the right idea, but the challenge wants you to return the result of the expression directly. Instead, you are doing two separate evaluations and then returning a true or false based on this. It's generally considered to be much cleaner code to avoid a situation where you have something like "if x is true return true otherwise return false".
Here's the line you're looking for:
return tiles.indexOf(tile) >= 0;
This asks if the index of the tile is greater or equal to 0. If this is true, then the tile is present in the tiles string. So this line essentially says "is the tile in the string?" and will return a true or false accordingly.
Hope this helps!
