I don't see where is my error. Please help me out...

ScrabblePlayer.java 
public class ScrabblePlayer {

  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 number = 0;
    for(letter : tiles.toCharArray()) {

Hi Modure,

Your solution confuses the method parameter called letter with a local variable in the for loop called the same thing.

You want to create a local variable within the for loop, compare that to the method argument/parameter, letter, and increment a local count variable. Once the loop has finished, return the count variable.

Something like:

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

Steve.
