getCountOfLetter method help

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

  public int getCountOfLetter(char letter) {

    return 0;
  }


  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;
  }
}
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 Maor

You have done great for the first part of the challenge. Next you need to use for loop to test each tile from tiles.

if the tile is equal to the letter input you need to add one number (increment) to the counter.

Oh.. PS you cannot just test if variable letter directly == to tiles since letter is a char and tiles is a string. Therefore you need to convert the string variable tiles to Char Array to be able to loop and test against letter variable.

I have tried to solve your challenge and here is the code I wrote to pass the challenge:

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

I hope this can help you a little.
