getTileCount method for the scrabble game

Here is my code, I know there is something small I'm forgetting here. I want the method to tell the user how many tile letters they have. Thanks!

public int getTileCount(char t){ int count = 0; for (char tile : mHand.toCharArray()){ count++; } return count; } }

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 t){
    int count = 0; 
    for (char tile : mHand.toCharArray()){
      count++;
    }
    return count;
  }
}

below is your code:

public int getTileCount(char t){
    int count = 0; 
    for (char tile : mHand.toCharArray()){
      count++;
    }
    return count;
  }

you increase the count for every tile in the hand. However, you only want to increase count if the character passed in as a parameter (t) is in the hand. you need to add an if statement that checks if the tile the loop is currently on is equal to the tile passed in:

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