2,268 Pointstry this:
public boolean hasTile(char tile) {
if ((mHand.indexOf(tile) >= 0)){
return true;
}else{
return false;
}
}

18,277 PointsThe if and else statement might not be necessary. Write less code as much as possible. A one liner like so " boolean has_tile = mHand.IndexOf(tile) != -1; return has_tile;", produces the same results.

27,272 PointsFirst of all you don't need to set a variable for hasTile at all. You can save some code and just return the boolean true or false value through an if/else statement.
You are using the right method, indexOf(), but your case is off. Also, indexOf() returns a -1 value when a char is not found in the string. This is in the video somewhere. Also, you don't need the quotes on the parameter of tile, because you want it's contents, not the literal word 'tile'.
I hope this helps!
