Getting count as the no. of characters in the word , and not able to increase the count if a character i appearing twice

Please check the code and let me know the corrections to made in the if block inside for each loop

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 aTile){
    int tileCount=0;
    for (char tile: mHand.ToCharArray()){
      if (mHand.indexOf(aTile)>=0){
      tileCount+=1;
      }
    }
    return tileCount;
  }
}

Hi there,

You were correct until here:

if (mHand.indexOf(aTile)>=0){

You are looping through your mHand as you have converted it to a charArray(). That's correct. At each loop, you are taking the next letter in the array and assigning that to your loop variable called tile. So, you want to see if the character you passed into the method as a parameter, aTile, is equal to any of the letters in your charArray. So you want to compare each tile with aTile and increment tileCount where they are equal.

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

I hope that makes sense!

Steve
