What is wrong with this syntax ?

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 counter = 0;
    for (char tile: mHand.toCharArray()) { 

     if (mHand.indexOf(tile) >= 0)
   counter = tile;
    }

     public int getTileCount(char letter) {
     counter = 0; 
       for (char c: mHand.toCharArray()){
         if (letter == c) {
           counter ++;
         }
       }

       return counter;
     }
}
