Having trouble understanding the "For Each Loop" challenge..

I don't play scrabble so I don't know how the game works. Only have a vague idea..

So I am having trouble understanding what I have to do in the next challenge. I don't understand what the challenge is asking me to do..I am pretty sure that once I understand what I really have to do I can add a method doing that.

Please help.

Let me give you direction: you have to write method getTileCount(char tile) that loops through tile in mHand and if this tile as argument equals to tile in hand, we increase counter...Does it make sense?

 public int getTileCount(char tile) {
     // cycle through tiles in hand
     // if tile in hand == tile in argument, then increase counter
     // return counter: number of tiles
  }
