Unknown error, And how is this not working?

I don't understand why this is not working! Can anyone explain this to me?

com/example/BlogPost.java 
package place.com.example;

public class BlogPost { 

}
Display.java 
import com.example.BlogPost;

public class Display {
  public static void main(String[] args) {
    // Your code here...
    BlogPost post = new BlogPost();
    System.out.printf("This is a blog post: %s",post);
  }
}

Remove place.

As mentioned, you essentially need to reverse the domain when using the package keyword. In our case, the domain is example.com. So, it would read:

package com.example;
