Java Java Objects Creating the MVP Counting Scrabble Tiles

please help how to get the number by enhanced for loop with conditional if statement?

I am stuck here, enhanced for loop + if statement

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; 

   if(tiles.indexOf(letter)==-1){
    return 0;
   }

   if(tiles.indexOf(letter)!=-1){
    for(char test: tiles.toCharArray()){
      if(test==tiles.charAt(i+1)){
        i++;
    }
   }


}

}
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 Tan,

Your method getCountOfLetter() starts with return statement, therefore the rest of the method is never going to execute. Also, you are using integer i, but this variable is not declared anywhere in you code.

You should check if your variable char test is equal to char letter passed in as argument. If it is, increment count. At the beginning count should be zero. At the end of the method just return variable count

Hope it helps.
