getTileCount - not sure if I understand what is being asked of me

I've created a method for getTileCount, but I'm still not able to pass.

What am I missing?

public int getTileCount() { tileCount = 0; for (char letter: mHand.toCharArray()) { tileCount += 1; } System.out.println("Tile count is:" + tileCount); return tileCount; }

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

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public int getTileCount() {
    tileCount = 0;
    for (char letter: mHand.toCharArray()) {
      tileCount += 1;
      }
    System.out.println("Tile count is:" + tileCount);
    return tileCount;
  }

  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;
  }
}

I had to read this challenge a couple of times. You don't want to count how many tiles the player has - there's no need to use a for:each loop to do that. You can just use the length() method for that! You're pretty close with your code but you need to pass a char in, then iterate over the mHand string.

The getTileCount method needs to take a char as a parameter. The for:each loop then iterates through the mHand string and counts how many instances of that char occur. So, if the player's hand was H E L L O, the method would be called like: getTileCount('L'); and it would return 2, the number of Ls in the hand. If the hand was T R E E H O U S E, getTileCount('E'); would return 3, and so on.

My solution looks like:

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

I hope that makes sense!
