Treehouse TeacherHi there, cesar! I received your request for assistance. You did the first part just fine, but I'm concerned that you may be misunderstanding what the challenge is asking. We want the program to take a group of letters and ask if the player has one of them in their hand. As hinted at in the challenge instructions, you will need to use the indexOf
method to do this. You will be looking for the index of the tile
inside of the tiles
string. If the tile is not found, the value returned by the indexOf
method will be -1 indicating that the tile was not found. So you can set up a comparison to check if the result of the indexOf
method was greater than or equal to 0. If it was, then the tile was found, otherwise it was not.
Note that while you can do this with if/else statements, this approach will not be accepted by the challenge. This should all be done in one line of code inside a return
statement.
I hope this helps, but let me know if you're still stuck!

this expression it is ok and
return tiles.indexof(tile)>=0;
must work as well...

Be careful because Java it's sensitive with the methods.
