Passing char and adding to mHand field.

If the method declares that it will not return a value (via void), then it should not return a value. This is not allowed:

public void addTile() {
   ...
    return isTile;
}

Either change your method declaration (to boolean) or return null.

I think I just had your same question, here was my solution.

<p>
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) {
      boolean isTile = mHand.indexOf(tile) >= 0;
      if (isTile) {
       return true; 
      } else {
       return false;
    }
}


</p>

Notice that you had the right idea, but were unsure what method to put it in. Side note, I think void methods might not need return lines. Also, I would like to hear someone explain void methods and return types if they have a chance. Thanks!

@Tom Sager i did that but I am being compeled to use += method to add chars to existing string. below is my code. @TJ note I should use the += method

public boolean addTile(char tile) { // Adds the tile to the hand of the player boolean isTile = mHand.indexOf(tile) >= 1; if (isTile) { mHand += tile; } return isTile;
