bad initializer for for-loo

Question

Why doesnt this code work, it keeps saying: 'bad initializer for for-loop'. Can you explain the reason to me?

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 counter = 0;

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

Hi Mads,

The problem is that you used tile from the getTileCount parameter list as the name for the first variable in the for each loop. Instead, consider declaring a new variable inside of the loop:

public int getTileCount( char tile ) {
      int count = 0;

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