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