Help with challenge?

I thought I was using the code right but I guess it doesn't recognize any of it and just asks me if I forgot to create the getTileCount method.

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() {
    int count = 0;
    for(char tiles: mHand.toCharArray()) {
      count++;
    }
    return count;
  }
}

Hi Joel,

You're extremely close, it looks like that all you're missing is an if-statement to check if the character is equal to the tile.

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

If you have any other questions feel free to ask! Hope this helps!

I passed the challenge with

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 count = 0;
    for (int i = 0; i < mHand.length(); i++) {
        if (mHand.charAt(i) == tile) 
            count++;
    }   
    return count;
}
}
