if will return true
or false
on it's own so instead of using it in an if
statement you can return it directly like this:
public boolean hasTile(char tile) {
return tiles.indexOf(tile) != -1;
}

If you're conviced that your expression is correct; just return it!
return tiles.indexOf(tile) != -1;
(I'll check it now - I used >= 0 rather than != -1) Edit: works fine - good work!
Steve.
