Don't know the next step - Slightly confused on what method I call and why

Explanation please.

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;
    }
}

He wants you to change the hasTile method.

You should check if the mHand string contains the char tile. A nice way to do this is by using the string method indexOf()

for example 

mHand.indexOf(tile)

Remember that this method returns an int. If it contains it will return 0 or bigger. If it does not contain the letter it will return -1.

Hope this helps.

Here is what I did:

public void addTile(char tile) {
        // Adds the tile to the hand of the player
      mHand += tile;

    }

    public boolean hasTile(char tile) {

      for(char letter : mHand.toCharArray()){

        if(letter == tile)
          return true;
      }
      return false;
    }
