Totally Lost on ScrablePlayer Challenge !!

Need some help with the 'For Each loop' implementation in this challenge.

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;
  }
}

Hi Shivang,

Let's start by making the getTileCount method signature. Since it's going to return a count, we'll set the return value as an int.

public int getTileCount(char tile) {
}

We want to return a count of the number of tiles a player has that matches the given tile.

public int getTileCount(char tile) {
  int count = 0;
  // for each letter in mHand
  //    if letter matches tile
  //      increment count
  return count;
}

If you need a refresher on setting up the for ... each loop, at about 1:08 in the video Current Progress, Craig explains how to do this.

Hope this helps,

Cheers
