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

I'm stuck, not sure what I'm doing wrong?

I'm not sure if I should use tile of mHand in the for loop?

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

public int getTileCount(){
    int counter = 0;
    for(char letter:mHand){
      if (mHand.indexOf(letter) >= 0){
        counter += 1;
      }
      return counter;
    }

  }
  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;
  }



}

You need to start by creating a method header that passes in a char argument and returns the count (int) and name it getTileCount so we have:

public int getTileCount(char tile){

}

Next we have to iterate through the characters of the String mHand and increment the count variable that you are to create, like this:

  for(char letter : mHand.toCharArray()){
    if(letter == tile)
      count++;
  }

After your for loop body just return the count.

...and don't forget to add a count variable before your for loop and increment the count during the loop.
