Trouble with For loop challenge. Appreciate help.

Don't play scrabble. And not sure which variables/strings to compare to determine a "match". I have no syntax errors but my tileCount returns 8 no matter, what so not making right comparisons.

private String mHand;

public ScrabblePlayer() { mHand = ""; }

public String getHand() { return mHand; }

public void addTile(char tile) { // Adds the tile to the hand of the player mHand += tile; } //modifier returnType nameOfMethod (Parameter List) public int getTileCount(char tile) { int tileCount = 0; for (char letter: mHand.toCharArray()) { if (mHand.indexOf(tile) >= 0) { tileCount += 1; } } return tileCount; }

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

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }
  //modifier returnType nameOfMethod (Parameter List)
  public int getTileCount(char tile) {
   int tileCount = 0;
    for (char letter: mHand.toCharArray()) { 
      if (mHand.indexOf(tile) >= 0) {
        tileCount += 1; }
    }
    return tileCount;
   }

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

You're very close! The issue is what you're checking in the if statement inside your for loop. Here's a way of checking if the letter matches the tile (specifically, you want to check if the chars match):

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

Hope this helps!
