Why bother defining getHand, addTile when i cant reference them?

I am stuck trying to create a loop to count the number of each letters tile in my hand. 1) i cant seem to reference any of my previous variables 2) i cant seem to use the same variable (tile in multiple spots of my getTileCount logic) unlike the Hangman example in class. Where we ref letter 4 times. public boolean applyGuess(char letter) { boolean isHit = mAnswer.indexOf(letter)>= 0; if (isHit) { mHits += letter; } else { mMisses += letter; } return isHit;

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(char tile) {
     int tileCount = 0;


     for (int letter: mHand.toCharArray()) {

        tileCount += letter;
  }
  return tileCount;
          }

}

You almost haved the only you need to check if the tile is equal to letter

public int getTileCount(char tile) {
  int tileCount = 0;


  for (char letter: mHand.toCharArray()) { // change the int to char
    if(tile == letter){ // <-------- here check if the tile is equal to letter
        tileCount++; // increment
    }
  }
  return tileCount;
}

thanks for your prompt response. why does my incrementor result in 845 vs yours which results in 8? the correct response is 1 so i am still digging a bit but i am unclear what was wrong with my incrementor logic

Well in your code you are increment each latter but in the challenge they wan to increment the specific char that is why you have to use the if statement
