What is wrong with my getTileCount methid? I am not able to see exact error in preview..

My code looks ok. There is some compilation error I can see in preview..

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

}

Very close! If you click the Preview button you will see the following compile error:

./ScrabblePlayer.java:27: error: variable counter might not have been initialized
         counter++;

Which suggests that you initialize your counter variable when you declare it:

int counter = 0;
