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

Courses Plus Student 7,180 PointsTry this Sachini Hansini Nawalaella:
public boolean hasTile(char tile) {
return tiles.indexOf(tile) != -1;
}
