Got stuck. Scrabble Player.

Please guys, anyone can help me out?

Thanks!

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public int getTileCount(char letter) {
    int tileCount = 0;
    for (char tile: mHand.toCharArray()) {
      if (mHand.indexOf(tile) >= 0) {
        letter = tile;
        tileCount += 1;
      } 
    }
    return tileCount;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }
}

Hi Thiago,

you are very close !

You need to modify your conditional if statement inside the for loop:

   if (mHand.indexOf(tile) >= 0) {
        letter = tile;
        tileCount += 1;
      }

Here you try to compare a String with a char. But you should compare a char with a char. But don´t panic, you have everything you need in this block of code :)

You already created a beautifull charArray of mHand in your for loop. This chars can be compared with the char "letter" you have as argument. For your if statement use the == operator to compare your letter with every char of the mHandArray. So your conditional if statement should look like this:

      if (letter == tile)  {
        tileCount += 1;
      }

I hope this will do the trick !
