java challenge question__i need help plz

this is the question==>>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..plz i would like your help with this question

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 void getTileCount() {
    for (char tile:mHand.toCharArray()) {
    System.out.println("here are them " + tile);
    if (mHand.indexOf(tile) > -1){
        mHand += tile;
      }  
    }


  }
}

Hello,

There are few errors in your code:

  1. You need to pass a char parameter to your method
  2. You need to compare Tile to the letter from loop
  3. You need the method to return an integer

Here is the code, hope it makes sense:

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