How do u get getTileCount to accept char?

Question

I have been trying to solve this challenge, I thought the method was accepting char since it was declared in for ( char tile: mHand.toCharArray()) Otherwise what is that doing?

ScrabblePlayer.java

public class ScrabblePlayer {
  private String mHand;

  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 String getTileCount() {
   String counter = "";
    for ( char tile: mHand.toCharArray()){
      char display = '-';
      if (mHand.indexOf(tile) >= 0 ) {
       display = tile;
      }
     counter += tile; 

    }
    return counter;
  }
}

Hey Alex,

I think I just answered the earlier question about this, but what the for loop is doing is looping through each character in your mHand.toCharArray(), which basically, it is breaking apart each letter or character in the string and then running the code in the loop beneath it.

Thanks.

I'm not sure if this is what you were meaning with your question, but to make getTileCount accept a character as an argument, we'd pass that as a parameter into it.

getTileCount(char letter)

Or something similar.
