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

I'm doing something wrong but can't figure out what

public int getTileCount(char tile) { int tileCount = 0; for(char tile: mHand.toCharArray()){ if (mHand.indexOf(tile)>=0) { tileCount ++;
} } return tileCount; }

I keep getting the message that char tile is already defined but if I remove it from the () at the beginning, I get the question did you remember to prompt. I'm misunderstanding something.

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

}

I think it is because you are using the same name that the parameter has. You could do it like this:

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

I hope that helps

That makes sense. Thanks! It worked!
