Hello mate,

I like your thinking and can see what logic you're trying to implement within the .hasTile(char tile) method. With just a few alterations you would have a correct implementation:

public boolean hasTile(char tile) {
    int hasTile = tiles.indexOf(tile);    // .indexOf(char c) returns a value of type int not boolean
    if (hasTile == -1) {    // == for test of equality not = for assignment
      return false;
    } else {
      return true;
    }
}

BUT, this is not the implementation the Treehouse Java test engine is expecting to see.

Hope this helps

Try this Sachini Hansini Nawalaella:

public boolean hasTile(char tile) {
    return tiles.indexOf(tile) != -1;
}
