Nice lecture from the brain-box Hive account@branx
Really enjoyed seeing this. However, if i may contrubute to this...

How about you use code block for your line of codes in order to make the codes more readable. To use it, just enclose your code in this (~~~ codes here ~~~)
Let me make a sample...

import javax.swing.JOptionPane;

public class Hello {
public static void main (String []args) {
    JOptionPane.showMessageDialog (null,  "hello steemit");

  }
}

This is just a simple Java program, the point here is how the code shows to the readers.

I believe this makes this lines of code more readable and Utopian-io moderator wouldn't reject your post for this reason.
