Why do i get a compiler error when I run this?

This is what is being asked.

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)
  {int count=0;
   for(tiles.toCharArray()){
 if(tiles.equals(letter)){
   letter+=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');
  }
}

Can you copy the compilation error here.

The first problem that is preventing it from compiling is you haven't set up your for loop properly:

for(tiles.toCharArray()){
  if(tiles.equals(letter)){
    letter+=count;}
  }
   return count;
  }

You need to do something like:

for (char tile: tiles.toCharArray() {

}

But there's some other problems here too. You're not comparing the letter to an individual tile, you're comparing it to the whole string of tiles. Also you're not incrementing your count variable, you're adding count to letter and that's not what you want.
