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

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.
