Freestyle Coding: Youtube

Published on 11 / 24 / 2024

Coding is hard. Really hard. It is for those whose brains are oriented in logic and creative solutions to complex problems. I encourage everyone to try coding once, if interested.

To learn coding best, I like to make programs that include variables and methods that are comedic or have emotional prominence. Therefore, when I am writing the code, I better recall how to implement the given methods and coding signatures.

This week, I was tasked with learning Polymorphism, ArrayLists, and Interfaces(fancy words, I know). While you may not understand everything in this code, it is apparent with codewords like "Youtube", "Subscribers", and prominent online figures' names that I tried to mimic Youtube's source code implementations! Coding is very creative, requiring lots of failure, problem-solving, and brainstorming. Below, you can scroll through my code!

	public static void main(String[] args) {
		ArrayList<Youtuber> youtube = new ArrayList<>();
		
		// create youtubers
		Youtuber jerma = new Youtuber("Jerma985", 965000, true, false);
		Youtuber charlie = new Youtuber("MoistCr1tkal", 16200000, false, false);
		Youtuber markiplier = new Youtuber("markiplier", 37000000, false, false);
		Youtuber sinjin = new Youtuber("Sinjin Drowning", 847000, true, false);
		
		youtube.add(jerma);
		youtube.add(markiplier);
		youtube.add(charlie);
		youtube.add(sinjin);
		
		printList(youtube);
		
		if (youtube.contains(jerma)) {
			System.out.println(jerma.getName() + " is still on Youtube.");
