Java Java Objects (Retired) Creating the MVP For Each Loop

How to solve this code challenge

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!

ScrabblePlayer.java
public class ScrabblePlayer {
  private String mHand;
  char tile;

  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() {

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

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 counter = 0;
    for(char c: mHand.toCharArray()){
      if(c==tile){
        counter++;
      }
    }
    return counter;
  }
}

Couple points you are incrementing count++ but you declared count as a char. You need to declare an integer to keep track of the matches.

You also seem to be trying to return the count (which is a char) through each iteration of the loop. This should not be returned till the count has finished (also returned as an int).

Anymore questions, just ask.
