Having problem with Challenge 2 in hasTile method

Code attached

The Bummer is :

Remember,if a string does not have a char, the indexOf method wil return -1

ScrabblePlayer.java 
public class ScrabblePlayer {
    private String mHand;

    public ScrabblePlayer() {
        mHand = "";
    }

    public String getHand() {
       return mHand;
    }

    public void addTile(char tile) {
        if(mHand.indexOf(mHand)>=0){
        mHand += tile;
        }
    }

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

It's ok , problem solved. I did modification as below . It works

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

}

Nice! Also, remember you can return the results of an expression.

return "hello".indexOf('h') >= 0;
