Stuck on tile counter problem.

I can't figure out how to start a counter every time a character matches and I've been trying forever. Any help is appreciated. Thanks!

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;
  }

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

  }
}

Your code should look like this:

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