Why I get a bummer, when my code is working perfectly?

Look at my getTileCount() method, this function is working perfectly in my IDE, so why it isn't accepted here?

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 letter : mHand.toCharArray()){
      count++;
    }
    return count;
  }
}

The method needs to accept a char variable, and you forgot to check if the letters match before increasing the count...

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