passing objects in methods

i'm not sure if i am thinking through this correctly. I would appreciate a bit of methodology here.

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
     String new tile  = mHand + tile; 

    }


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

Hi Neil,

First task wants you to pass a tile to mHand

public void addTile(char tile) {
      mHand += tile;
    }

Second task wants you to proof whether the tile is in the mHand or not and return true if tile is in mHand or false if not

public boolean hasTile(char tile) {
      if (mHand.indexOf(tile) < 0) {
        return false;
// indexOf() method returns -1 if the char is missing
}
// if indexOf returns 1, the tile is inside mHand 
        return true;
}

You are very welcome. I review the complete java course again. It is a lot of work, but I understand so much more now. And the challenges are very complex in the beginning and now they start to make much more sence ...
