Not sure what argument to pass into function here.

The prompt calls for a method, which I've added at the end, that can accept a char. I'm trying to pass in "tile" but am getting error messages. Anyone know why?

public class ScrabblePlayer {
  private String mHand;
  private int tileCount;


  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }

  public void getTileCount(tile) {
    for (char tile: mHand.toCharArray()) {
      if (mHand.indexOf(tile) >=0) {
      tileCount += 1;
      }
    }
  }
}

Also not sure where to initialize the variable tileCount. Would appreciate an explanation of how to do this!

Hello, you're close on this, just a few minor errors, first off, I'd name your char in if for statement different than the variable that is expected in the method signatures, this just makes things less confusing, so instead something like for(char letter: mHand.toCharArray())

Also, if your if statement see if that variable you created in your the above for statement is equal to the character that the origional method had passed in. so in the chase of letter it would look something like If (letter == tile).

You actually initialized the variable in the correct spot, it looks like you just called the variable a name that was already taken, and that could have confused your code.

It should look something like this.

public int getTileCount(char tile){
    int count = 0;
    for(char letter : mHand.toCharArray()){

      if(letter == tile){
        count++;
      }
    }
    return count;
  }
}

Looks like you were slightly over thinking this one, I do the same often.

Thanks, let me know if this helps or not and I'll give it another look.
