Expected 0 but got 1

Why is the method returning 1 instead of 0 for the hand "sreclhak" and tile 'n'?

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;
  private int numberOfTiles=0;

  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){
    for(char letter: mHand.toCharArray()){
      if (tile==letter){
        numberOfTiles+=1;
      }
    }
    return numberOfTiles;
  }
}

Honestly? I don't really know. What I can tell you is if I move the original declaration of your numberOfTiles variable inside the function, it passes. Take a look:

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

There's no other code I see that would change that value. Maybe it's a quirk of the challenge? But I hope this helps! :sparkles:
