A little bit lost here, can someone help, please?

Strings and Chars. stage 2 challenge 2.

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 false;
      boolean hasTile = mHand.indexOf(tile) >= 0;
      return true;
    }
}

You have two return statements inside your function without providing a way around the first one to get to the second. As a result your function will always return false. You can get around that by doing:

    public boolean hasTile(char tile) {
      if (mHand.indexOf(tile) >= 0) {
        return true;
      } else {
        return false;  
      }
    }

With that if statement it will allow one of the two boolean options to be returned.

You can also simplifying the hasTile() method a bit and do something like:

public boolean hasTile(char tile) {
    return mHand.indexOf(tile) >=0;
}

You had the correct idea in your code, just needed a few minor syntax adjustments.
