Now in your new method, have it return a number representing the count of tiles that match the letter that was passed in to the method. Make sure to check Example.java for some example uses.

I've tried hard to do it, i know its pretty easy, i just need some tips on what exactly is needed to be done. thanks

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){
    return 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');
  }
}

Hi David,

You can start with initialization of int variable which will keep number of matches, lets say int countTiles with starting value equals to 0. Then you could convert variable tiles to Array of chars (check method toCharArray() ). Use FOR statement to check if chars in this Array are equal to argument letter. If it is, increment countTiles. At the end, return countTiles. If somethings not clear, let me know.

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

This is what i have but its still not working
