Code Challenge trouble not sure why my code wont pass?

So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, 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;
  }
}

//My code attempt

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 String getTileCount () { String count = ""; for (char tile: mHand.toCharArray()) { char display = '-'; if (mHand.indexOf(tile) >= 0) { display = letter; } count += display; } return count; }

'''javascript public boolean hasTile(char tile) { return mHand.indexOf(tile) > -1; } '''

What are you telling it to return? What you want to do is make variable that stores the boolean of that 'mHand.index....' statement. Then you use that variable as a conditional in an if statement similar to how we did in the lesson. I think you're misunderstanding the question and also the function of return. Return is used to return a value to the console or in other words the user. The way you have it now you would probably get an error. Test it out in the workspace.
