I am stuck on this for each loop part please help!

I do not understand the part of the directions where they ask me to increment the counter if the tile matches!

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

    return count;
  }
}

Because you're using char tile in the for loop, it will take precedence over the paramenter tile and we don't want that to happen. You should give it a different name, then inside the for loop you check whether it is equal to tile and increment count if it is.
