What is wrong with my loop

I cant figure it out

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=0;

    for (char letter: mHand.toCharArray()){
      letter=tile;
      if (mHand.indexOf(letter)>-1)
        counter++;
    }
    return counter;
  }
}

counter += 1 is the same as saying counter++

Hi Shree,

It looks like you're really close. In the if-statement we can check if the letter matches the tile -- that is, the chars match.

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

If you have any other questions feel free to ask! Hope this helps!
