casting as BlogPost and returning the title

I'm going to have to sleep on this one - I think I see that we have to typecast the obj into a more specific type, but we need to return a String title (or result) right - does the obj, once typecast into a BlogPost, have an author, title, description and so on?

Well the below doesn't work. 

public static String getTitleFromObject(Object obj) {
    // Fix this result variable to be the correct string.
    String title = "";
    if(obj instanceof String){
      title = (String)obj; 
    }
    if(obj instanceof BlogPost){
      obj = (BlogPost)obj;
      title = obj.mTitle;
    }
    return title;
  }
