What should I do?

Help me,please!

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;
  }

  //I have a problem here
  public int getTileCount(char name) {
    int counter = 0;
    for (char letter : ) {
      counter++;
    }
    return counter;
  }
}

I can't tell from the question exactly which exercise this was, but I'll take a stab at the one that I think it might be. I think the assignment was to make a method that will run through the hand and tell you how many items were in the hand. If so, you create this method that returns an integer, you create a counter integer and set it to zero, then you use the for loop to iterate through the characters of the hand. We use the toCharArray() method to turn the hand into an array of characters. Each time a letter equals a tile, we increment the counter by one, finally returning the counter.

public int getTileCount(char tile) {

    int counter = 0;

    for (char letter: mHand.toCharArray()) {

      if(letter == tile) {
            counter += 1;
        }
    }

   return counter;
  }
