The hand was "sreclhak" and 'e' was checked. Expected 1 but got 8.

I don't understand why it isn't filtering the incorrect letter through? It should come out as one.

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 tile) {
    int counter = 0;
    for (char letter : mHand.toCharArray()) {
      if (mHand.indexOf(tile) > -1) {
        counter ++;
      }
    } 
    return counter;
  }

}

Hi Noah-

You're so close! The problem comes in on the if portion inside your for loop. What you have now says: "For each char in mHand, if the tile exists ANYWHERE in mHand, add one to the counter" Because the char does exist in the hand, it adds one for each char in the hand (8);

The fix to this is: "For each char in mHand, if the tile matches the char, add one to the counter"

Try:

  public int getTileCount(char tile) {
    int counter = 0;
    for (char letter : mHand.toCharArray()) {
      if (letter==tile) {
        counter ++;
      }
    } 
    return counter;
  }

Thank you so much! I didn't realise it was such a simple task. I have a habit of making things harder than they should be :D!
