Hi Rafia,

BlogPost.java

//declare package
package com.example;

//create class
public class BlogPost{



}

Display.java

import com.example.BlogPost;


public class Display {
  public static void main(String[] args) {
    // Your code here...

    BlogPost blogPost = new BlogPost(); // create blogPost object

    System.out.printf("This is a blog post: %s", blogPost); // print blogPost using printf

  }
}
  1. declare package com.example in BlogPost.java
  2. Make public class BlogPost in BlogPost.java
  3. import com.example.BlogPost in Display.java
  4. make blogPost object and use printf to print output

Hope this helps! If you have any other questions -- just ask!

The class that has to be executed must have the main method

public void main (String [] args) { }

Your program can have multiple other classes without the main method. But you have to reference them in your "main" class to be executed ...
