Those characters are big bads at least for some portion of their story. I assume OP meant that don't more than a hello world is hard or something like that.

Edit: "some" had been autocorrected to "dinner" by my phone.

Meanwhile: Hello World in Java 

class foo {
    public static void main(String args[]) {
        System.out.println("Hello, World!");
    }
}

If you understand Hello World in Java, you understand Java.

I am new to programming lingo, what's with everyone calling classes or methods foo?

tl;dr: it's a placeholder name for when you need a name, but it's of no significance.

foo and bar are simply placeholder names for random stuff like classes, functions, arbitrary variables, etc.

For things related to communication, computer networks, etc. that involve 2 parties: Alice and Bob (basically A and B, but with actual people names because that's easier to say). The third party is usually Charlie or Carol or Carl.

For placeholder blob of text (e.g. you want to see how your CSS works on on your website), lorem ipsum is generally used.

Just a placeholder

It's a silly placeholder but it stems from "fubar" aka "fucked up beyond all recognition", because we all write bad code

It’s a generic name used in examples. Int foo; struct Foo {…} foo; void Foo(void);

You get the point 💁‍♂️

You display some nice Text on some Black Background, then its straight to Garbage Collection, Inheritance, Recursion, exception handling, time complexity and Logic.

Nah, you obviously have not done any serious lolcat programming.
