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
this.tiles += tile;
}
public boolean hasTile(char tile) {
// TODO: Determine if user has the tile passed in
boolean isTile = tiles.indexOf(tile) != -1;
if (isTile) {
return isTile;
} else {
return isTile;
}
}
}

public boolean hasTile(char tile) {
// TODO: Determine if user has the tile passed in
return *expression goes here*;
}
This way you still have a method and you still have something to return; an expression to evaluate.
