Java Java Objects Creating the MVP Counting Scrabble Tiles

I'm unable to understand how to solve this problem.

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.

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){

  }
}

Hi Narender, one way to handle this would be to determine how many times the tile appears in the tiles string by converting it to an array of char, and using a for loop to increment over it, keeping a count of each time that the tile is equal to the letter given to the method.

public int getCountOfLetter(char letter) {
  int count = 0;
  for (char tile : tiles.toCharArray()) {
    // increment count if letter is the same as the tile, your task :)
  }
  return count;
}
