691 PointsHelp, I'm stuck at Srabble tiles Task 2!
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 is uses the index of a char in a String.
I tried that method that is written in the code but it says: Bummer! While you could definitely solve this using an if statement, try returning the result of the expression.
Thank you.
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) >= 0) {
return true;
} else {
return false;
}
}
}

return tiles.indexOf(tile) >= 0)
instead of
if (tiles.indexOf(tile) >= 0) { return true; } else { return false; }
if this answers your question, please mark the question as answered.

1,577 PointsCan someone explain me the part, where I have to use ">= 0"?? .... Why simple tiles.indexOf(tile) don't work??
Craig Dennis
Treehouse TeacherHi ondrejhavazik !
indexOf will return -1 if the value is not found in the String.
Does that make sense now why it has to greater than or equal to 0 (zero is the first character)?

with this workspace you must be careful not to add or delete any brackets. it doesnt work the same as an IDE. the syntax errors dont do much either it just points with the " ^ "

Treehouse TeacherWhat's the expression? That's the part you've got in the
ifstatement between the parenthesis.
