PLEASE help

i have no idea what the question is trying to ask.. why would a counter method accept a char?? \is it not asking to increase a counter for every tile? the question also says " increase a counter if it matches" ??? if what matches lol again is it asking to increase a counter for every tile in the hand or.....

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 count = 0;
    for (char tile: mHand.toCharArray()) {
     count += 1; 
    }
    return count;
  }

}

You are trying to find out the count for a specific tile in a hand so your method should accept a parameter of type char for the tile. Also, you need to increment count only if a character in mHand matches the given tile:

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