Please help. I don't know where the mistake is?

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 each: mHand.toCharArray()){
      if(mHand.indexOf(tile) >= 0){
        counter++;
      }
    }
    return counter;
  }
}

Close. But they want the function to see how many times a given tile is in mHand:

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

So each time through the loop you need to compare a tile from the hand (which you have the loop put in the local variable each) to the tile passed to the function.

You do not want to know the position(s) of tile in the hand, so no need to mHand.indexOf(tile).
