What does this question mean?

Question

I don't know what the question means by "Increment a counter if it matches." I don't know why I need to increment, what a counter is, or what it is matching to.

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 getTileCount() {
    for (char tile: hasTile.toCharArray()) {
      //increment counter if it matches.
    }
    return /*count*/;
  }
}

Hey there, what the question is basically asking you to do is create a method that accepts a Char as an argument, and in the body of the method check and see if that character is contained in the player's hand.

We can do this by.

public int getTileCount(char tile) {
    int counter = 0; // we initalize our int counter here
    for (char letter : mHand.toCharArray()) {
      if (tile == letter) { // check to see if the the char we're currently check matches the tile we are looking for
         counter++; // increment counter, which is now one
      }
    }
  return counter; // return a int representing how many times the letter that we searched for was found 
}

Should do the trick. Let me know if there's anything else I can further clarify.
