Java Java Objects Creating the MVP Counting Scrabble Tiles

Create method getCountOfLetter that returns an int and requires a parameter of type char named letter. Make it return 0

public int getCountOfLetter(char letter) { int count = 0; for(char tile: tiles.toCharArray()){ if( tile == letter){ count++; } } return count; }

ScrabblePlayer.java
public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;

  public ScrabblePlayer() {
    tiles = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    tiles += tile;
  }

  public boolean hasTile(char tile) {
    return tiles.indexOf(tile) != -1;
  }
}
  public int getCountOfLetter(char letter) {
    int count = 0;
    for(char tile: tiles.toCharArray()){
      if( tile == letter){
        count++;
      }
    }
    return count;
  }
Example.java
// This code is here for example purposes only
public class Example {

  public static void main(String[] args) {
    ScrabblePlayer player1 = new ScrabblePlayer();
    player1.addTile('d');
    player1.addTile('d');
    player1.addTile('p');
    player1.addTile('e');
    player1.addTile('l');
    player1.addTile('u');

    ScrabblePlayer player2 = new ScrabblePlayer();
    player2.addTile('z');
    player2.addTile('z');
    player2.addTile('y');
    player2.addTile('f');
    player2.addTile('u');
    player2.addTile('z');

    int count = 0;
    // This would set count to 1 because player1 has 1 'p' tile in her collection of tiles
    count = player1.getCountOfLetter('p');
    // This would set count to 2 because player1 has 2 'd'' tiles in her collection of tiles
    count = player1.getCountOfLetter('d');
    // This would set 0, because there isn't an 'a' tile in player1's tiles
    count = player1.getCountOfLetter('a');

    // This will return 3 because player2 has 3 'z' tiles in his collection of tiles
    count = player2.getCountOfLetter('z');
    // This will return 1 because player2 has 1 'f' tiles in his collection of tiles
    count = player2.getCountOfLetter('f');
  }
}

Hello! If I understand this question correctly, they only wanted you to begin the method and make it return 0. You have actually completed the whole method. In the next step, this code should be the answer. For now, that method should probably look like this:

public int getCountOfLetter(char letter) {
return 0;
}

Thank you!
