So I keep writing the following and getting the "cannot find symbol" error, am I writing this if/else statement correctly? Does this even require one? Code below. Am I missing something?
public boolean hasTile(char tile) {
if(addTile) {
return true;
} else {
return false;
}

This could be used, but the "addTile()" method has a void return type. Which means it doesn't return anything. in order to use "if (addTile(char))" the "addTile()" method would have to have a boolean return type. There's more to it, but that's how it would work.
Answer: The challenge is asking you to do a check to see if the "mHand" variable contains the tile that was passed into the method. There are two ways to do this. You could either check to see if the string ".contains()" the tile (more difficult, more steps needed) or simply to check to see the ".indexOf(char)".
NOTE: .indexOf(char) returns a value of 0 or greater if the string has that char in it. If not, it would return -1. Knowing this, a simple comparator will do the trick.
If this isn't clear enough or maybe you have a question, please, I encourage you to respond. :)

Thanks for all your help, man!
