Need Help with Java Challenge: For Each Loop

Question

I have been tasked this: So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, thanks!
This is the given code:
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;
  }
}
I don't know how i am supposed to do this, plesae help.

Let me give you direction: you have to write method getTileCount(char tile) that loops through tile in mHand and if this tile as argument equals to tile in hand, we increase counter...Does it make sense?
java  
 public int getTileCount(char tile) {
     // cycle through tiles in hand
     // if tile in hand == tile in argument, then increase counter
     // return counter:
  }
