Don't know what I am doing wrong on getTileCount challenge and I'm out of ideas.

Question

What am I over looking.

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 count = 0;
    for(char letter : mHand.toCharArray()){
      count += 0;
      if(mHand.indexOf(letter) >= 0){
        count += 1;
      }
    }
    return count;
  }
}

Hello, you're close on this one! It just needs a few tweeks, first off your count += 0; isn't adding much to the code, you can leave it there if you want but so to make the code cleaner I'd recommend taking it out.

Then really the only problem with your code was your if statement.

You should adjust it so that it checks if the char letter that you created in your for loop is equal to the tile you are having the method check for.

It should look something like this.

public int getTileCount(char tile){
    int count = 0;
    for(char letter : mHand.toCharArray()){

      if(letter == tile){
        count++;
      }
    }
    return count;
  }
}

Overall, it looks like you were just over thinking the problem, and pretty much had it yourself.

Thanks, let me know if this helps or not and I'll give it another look.
