Don't know why my method getTileCount() in the ScrabblePlayer Java challenge isn't working.

Hello guys, according to the challenge, my code isn't working the way it should. Can someone please pinpoint what's wrong? Thanks!

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 count = 0;
  public int getTileCount(char tile){
    for (char letter : mHand.toCharArray()){
      if ( letter == tile ){
        count += 1;
      }
    }
    return count;
  }
}

João,

Actually, your code should work as it is. However, you would not want count to be a public member variable as it could be accessed from outside the class violating encapsulation. In order to make it pass the test, you can place the count declaration into the method call. Again, your code is logically correct and works if compiled in Eclipse. The test must just be not accounting for your specific implementation or is forcing you to think about how to use variables in a way that does not violate encapsulation. i.e.

       public int getTileCount(char tile){
          int count = 0;
          for (char letter : mHand.toCharArray()){
             if ( letter == tile ){
                count += 1;
             }
          }
       return count;
      }

Hope this helps.

Regards,

Chris
