counting-scrabble-tiles problem

I cann't catch the answer!!!!!!

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;
    char v = '';
    for (char letter1 : tiles.toCharArray()){
    if (tiles.indexOf(letter) == letter1)
      v = v + letter;
    }
  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');
  }
}

Hi Hatem...

You need to work on the getContOfLetter method. It basically asked you to increment your int count variable (count++) IF the letter match tile from tiles. The code should be like this:

public int getCountOfLetter(char letter){
    int count = 0;
    for (char tile : tiles.toCharArray()) {
      if (tile == letter) {//<-- IF tile is equal to letter then count will be incremented by 1:
        count++;
      }
    }
    return count;
  }

I hope this will help a little
