Now and then when coding you come up with something just awesome.
Although Java is not exactly my strong point, I’ve become more and more familiar with it to the point I can now write classes with multiple sub-classes with inheritance, etc. The best thing about this now, is I can imagine the whole thing and create just the one class to cover everything. Just like I do in C++.
Here’s a snippet:
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
/*
* Below is a fabulous piece of code that does wonders the universe has never seen before.
* All keys on the keyboard where gently pressed throughout as not to cause any
* disturbance whatsoever within the vast cosmos.
* Of course the old code will soon be on its way to code heaven in the shredded pieces
* it was coded in, un-loved and forgotten for all time. Sad really with a brilliant ending.
