     public static String getTitleFromObject(Object obj) {
  String result = "";
    if(obj instanceof BlogPost){
      BlogPost blog=(BlogPost)obj;
    result=blog.getTitle();
    }

You removed the first check for the previous string cast. The second part need both of them

if(obj instanceof String){
    result = (String) obj;            
}
else if(obj instanceof BlogPost){
  BlogPost blog = (BlogPost) obj;
  result = blog.getTitle();
}
