I can't solve the challenge

Question

Hi! I don't know what I should write to proceed. I need to do this: 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.

Can someone help me please?

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 int getCountOfLetter(char letter) {
    return(0);
  }

  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');
  }
}

The code you're looking for is something like this:

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

Good luck!

Hi,

You must break the tile String into characters and loop through all to find how many of them are equal with the char passed as a parameter in the method you've written.

You can do this in 2 ways: This way,by using a foreach to loop through tiles and an if to check the equality: public int getCountOfLetter(char letter){ int counter = 0; for(char tile : tiles.toCharArray()){ if(tile == letter){ counter++; } } return counter; }

Or by using streams which you can learn by watching https://teamtreehouse.com/library/introduction-to-functional-programming :
