Can someone help me with this task please?

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;
  public int counter;
  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 letter : mHand.toCharArray()) {
  counter += 1;
     return counter;
  }

  }
}

You need to add a char parameter to your method heading and increment the counter only if the tile in each iteration matches what was passed in. I can break it down for you more if you need me to.

Okay it looks like your for loop is already in place so now inside you need to add an if statement that will ck to see if the current iteration matches the char that was passed in, if it does then increment the count variable that you created. After the for loop ends simply return the count. Like this:

public int getTileCount(char tile){
   int count = 0;
   for(char letter : mHand.toCharArray()){
      if(letter == tile){
         count++;
      }
   }

   return count;
}

I just tested the code and it works. You may need to check where your curly braces are and make sure that your return statement is in the right place. I will give you the entire code to see where my return statement is:

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 letter : mHand.toCharArray()){
      if(letter == tile){
         count++;
      }
   }

   return count;
}



}
