I solved it very quickly using an "if" statement, however, I'm sure as you've noticed, the directions specify no "if" statements allowed. At first I thought, this is so stupid, in order to determine if something is true or false, you have to use an if statement somewhere. So, I figured, I guess I'll have to use a method with an "if" statement built in. Seeing how you used the "indexOf" method, I thought I would try that first. By pairing that with the "charAt", ".equals", and "Character.toString()" methods, I got it to work. However, I wasn't satisfied with the solution. Sure it worked great, provided it could find a character, but it would create a syntax error if it didn't find the char (index == -1). So, despite that passing the code challenge I decided to look for something else. I finally settled on this solution.
public boolean hasTile(char tile) {
return (tiles.indexOf(tile) >= 0);
}
Essentially the way this works, is, if index == -1, (char not found), it will return false, if it found the char (index will be 0 or greater), return true. Hope it helps
