I keep getting an error of cannot find symbol when trying to do boolean isTile = addTile.indexOf(tile);

Question: 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.

Error msg: ./ScrabblePlayer.java:20: error: cannot find symbol boolean isTile = addTile.indexOf(tile); ^ symbol: variable addTile location: class ScrabblePlayer

AddTiles is a method with no return value. The variable this.tiles is the String representing all of the tiles that this player has. Try that with indexOf.

indexOf will return -1 if the value is not found in the String as such your code should evaluate whether the String is greater than or equal to 0 i.e. is a char found.

I would write something like

return tiles.indexOf(tile) >= 0;

Let me know if this answers your question.
