Java Java Objects Creating the MVP Counting Scrabble Tiles

I don't understand if he wants me to create for loop and an if statement, or just a for loop or an enhanced for loop.

I just don't understand I have tried a lot of solutions.

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

It looks like you have a good start but a bit more work to do. Here's a few hints:

  • you might need a variable to hold the count
  • you might want to use a different name (than the argument) for the loop variable
  • you'll need to compare the loop variable against the argument
  • if it matches, increase the count
  • remember to return the count after the loop finishes

Thank You! Honestly I edited my Code but it still doesn't run.

You won't need "indexOf" for this. You want to increment the count each time the "tile" is the same as "letter".

And the "return" should come after the loop, and be the last thing in the method.
