Java Java Objects (Retired) Creating the MVP For Each Loop

I am getting no compiler errors, but my code doesn't pass?

It says that I didn't creat the getTileCount method that accepts a char.

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public int getTileCount() {
    int Count = 0;
    for (char tile: mHand.toCharArray()) {
       Count = Count + 1;
    }
    return Count;
  }

  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;
  }
}

Hi Spencer,

It looks like you're really close! But, try adding a char tile argument to getTileCount() and an if-statement, inside the for-each loop, to check if the letter matches the tile, then add 1 to the count.

public int getTileCount(char tile) {
   int count = 0;
    for (char letter: mHand.toCharArray()) { 
      if (letter == tile) {
        count += 1; }
    }
    return count;
   }

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

The goal of this challenge is that getTileCount will be passed a character. You want to check how many occurrences of that character are in you hand. 

// the character you are checking for is passed in
public int getTileCount(char tileToCheck) {
    int Count = 0;
    for (char tile: mHand.toCharArray()) {
        // TODO: if tile is equal to the tileToCheck parameter, increase count
       Count = Count + 1;
    }
    return Count;
  }
