For Each loop

Hi,

I'm not entirely sure what this task is asking me to do, does it want me to count how many tiles of each letter the player has?

Also, I'm a bit confused as to how I use a For Each loop to do this. Any help would be greatly appreciated.

Thanks.

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 int getTileCount(char letter) {
  int counter = 0;

    for( char tile : mHand.toCharArray()){

      if(tile.indexOf(letter) >= 0) {

      counter++;
      }
    }
    return counter;
  }




}

Very close!

You want to check how many times the tile is in the hand, so you loop over each letter in the hand and compare it to the tile passed in.

Instead of seeing if it exists anywhere in the hand, why not check to see if the tile equals the letter?

Hope that helps!
