Challenge Question

so I wrote this for the challenge and it is still telling me to create a new method for getCountOfLetter, was wondering if anyone could help assist on what I am missing.

public getCountOfLetter(char letter) { int count = 0;

}

}

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 getCountOfLetter(char letter) {
    int count = 0;

  }


}
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');
  }
}

They ask you to create a method that returns and int, your method does not return anything. Also it has no return type defined, all methods, even ones who don't actually return a value (void methods) need to have a return type defined.

If you add a return type of int (you can take a look at the other methods for examples of how return types are meant to look) and return the number 0 instead of creating a variable to hold it, then you will be able to pass the task.
