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;
      }
    }
}

Hi Devin,

Shouldn't you also need to call the indexof method on the mHand variable?

if (mHand.indexOf(tile) >= 0) ...

I don't think you need to have the condition >= 0 because if tile is not found in mHand, the return value is -1, which is false.

Devin;

It appears that your posts are showing up in the forum twice. I answered this question in your previous post here.
