We need a bit more information as to what part of your code you need help with. I'm guessing that you're referring to the compile error in your "hasTile" method.

The following statement returns a numeric value of the location of the tile (char) in tiles (String): tiles.indexOf(tile)

The if statement needs a boolean expression (something that returns true of false). Luckily the "indexOf" method returns a -1 if no match was found. Thus you can change your code accordingly:

if(tiles.indexOf(tile) != -1)
{
    return true; 
} else {
    return false;
}

Since we are only interested in the result of the if statement we can shorten our code:

return tiles.indexOf(tile) != -1;

We are asking tiles (String) where in it's list is tile (char). If it returns -1 it means that the tile (char) is not listed in tiles (String).

For more information you can have a look documentation provided by Oracle: https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#indexOf(int)
