Why is this error message: "Bummer! Hmmm, remember that you can add chars to an existing String using the += method."

on this piece of code: mHand += letter; ?

ScrabblePlayer.java 
public class ScrabblePlayer {
    private String mHand;

   public void addTitle(char letter){
        mHand += letter; 
  }

    public ScrabblePlayer() {
        mHand = "";
    }

    public String getHand() {
       return mHand;
    }

    public void addTile(char tile) {
        // Adds the tile to the hand of the player

    }

    public boolean hasTile(char tile) {
       return false;
    }
}

I think the main problem is the mis-type in your method name. It's called addTitle, rather than addTile. Probably the test can't fund the right method to carry out. You can use the code that you've written, but put it under the comment in the example you've given.

It wants you to make the method add to the existing hand of tiles. Simple code would be to say:

mHand = mHand + tile;

// the short hand way of doing this is:

mHand += tile;

make sure you do this inside the method addTile()
