You're using a wrong variable when calling the printf method. You use the class name instead of the variable name. Make sure you go back and review classes if needed. Craig does amazing job explaining them. I've also did some explanation myself here: https://teamtreehouse.com/forum/unfortunately-the-app-has-stopped-working-2

So it should be System.out.printf("This is a blog post: %s", display); ???

I think that is right but I think that the problem is where I tried to instantiate a new BlogPost

Not really. It should be:

BlogPost blogPost = new BlogPost();
System.out.printf("This is a blog post: %s", blogPost);

I STRONGLY recommend you open the link I provided and also go back in videos. It seems you have quite the issue with classes. They are the core of java so you MUST clear that problem.
