Java problems with Packages...I'm convinced I'm right...computer disagrees.

So... I was on the Packages Code Challenge on Java Data Structures and I was on task 4 and this was the question:

Now in the main method of Display.java, instantiate a new BlogPost. Use System.out.printf to print out "This is a blog post: %s" and pass in the newly created BlogPost object to replace the string formatter.

I did it, just like in the video and I got some compiler errors: 

./Display.java:4: error: illegal start of expression
    import com.example.BlogPost;
    ^
./Display.java:4: error: not a statement
    import com.example.BlogPost;
                      ^
./Display.java:5: error: cannot find symbol
    BlogPost blog = new BlogPost();
    ^
  symbol:   class BlogPost
  location: class Display
./Display.java:5: error: cannot find symbol
    BlogPost blog = new BlogPost();
                        ^
  symbol:   class BlogPost
  location: class Display
4 errors

I literally copied what the video said, and I got the same thing. I looked it up on the forum but there were no posts on this so...do I have a problem?

Here's my code: Display.java

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

  }
}

If anyone knows the answer to the problem that would be awesome.

Thanks Treehouse! ~ Eleeza

Your import statement needs to be at the top of the file, outside of the class.

import com.example.BlogPost;

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

Hi, thanks for the response, but it didn't work for me. I don't know if this is a technical issue with my computer or something...maybe?

I got 3 out of the 4 errors again:

./Display.java:1: error: BlogPost is not public in com.example; cannot be accessed from outside package import com.example.BlogPost; ^ ./Display.java:6: error: cannot find symbol BlogPost blog = new BlogPost(); ^ symbol: class BlogPost location: class Display ./Display.java:6: error: cannot find symbol BlogPost blog = new BlogPost(); ^ symbol: class BlogPost location: class Display 3 errors

But anyway, thanks for responding :)

Looking at the error, I'd go back to the BlogPost file and make sure that you are declaring the class as public.

package com.example;

public class BlogPost {

}
