Java Java Objects Creating the MVP Counting Scrabble Tiles

Scrabble

You'll need to use your skills to loop through each of the tiles, use an equality check, and then increment a counter if the tile and letter match. You got this!

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.


what did i do wrong?

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 howMany = tiles.indexOf(letter) ;
    return howMany;
    for (char letter : tiles.toCharArray()) {
    if (tiles.indexOf(char letter) != -1) {
    tile += letter;  
    }
    }
  }
}
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');
  }
}

public int getCountOfLetter(char letter) {
    //initialize a variable to keep track of the count
    int counter = 0;
    //Loop over the tiles
    for (char tile : tiles.toCharArray()) {
        //If the tile equals the letter, we increment the count
        if (tile == letter) {
            counter++;
        }
    }
    //return the count
    return counter;
}
