Help With Java

Question: Can you also please help me write out the hasTile method? It should return true if the hand has the tile, and false if it doesn't. Thanks!

My Code:

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 + mHand;

    }

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

Also remember you can just do:

return mHand.indexOf(tile) >= 0;

Thanks Craig, I thought the code looked a little bit sloppy.

Devin;

In your if conditional check you aren't referencing anything to index tile against. You need to use mHand.indexOf(tile) to check to see if mHand has a tile in it.

Does that make any sense?
