Java for Fucking Idiots: Learn the Basics of Java Programming Without any experience!

IntelliJ . Google it. Download the community edition. Move on with your
life.
It’s raw !
While I do think it’s worthwhile to know how to compile and run Java code
manually, I don’t think it’s a good fit for this book. But I’ll point you in the
right direction.
From the command prompt…
> javac HelloWorld.java
Would create a bytecode file called HelloWorld.class
> java HelloWorld
Would then run that program using the generated bytecode.

Or don’t. I don’t care. You really don’t need to stop and read more on this
topic unless you’re paranoid about learning how to compile & run Java
code at a very low, manual level.

Some would consider this part to be the “basics,” but I don’t fully agree.
Sure, it’s basic, but does a beginner need to understand it to start coding in
Java? To get their feet wet without hating their life?
Nope. IDEs.

CHAPTER 2: HELLO,
WORLD!
For their first program, most people do something called “Hello, world!”
Here’s how you’d do it.
print
(
"Hello, world!"
)
Done! Hah, just kidding. That’s Python. We’re in Java land, which means
we need to do 2x the work to get the same fucking result.
Okay, here’s what you do. Create a file called HelloWorld.java
Put this inside of it:
public class
HelloWorld {
//Called when the program is run

public static void
main (String[] args) {
System.
out
.println(
"Hello, world!"
);
}
}
Compile it.
Run it.
The program spits out “Hello, world!”
Wow. Great. That was both uninteresting and didn’t teach you much. I kind
of hate this program but it’s a rite of passage, in a sense.
There are a few things I want to highlight. Not with a highlighter, just with
words.

First, in English, we put periods at the end of our sentences. You’re don’t
want to do that in Java, as a period is very different. Instead, use a
semicolon.
This is a semicolon:
;
Yeah, it’s that thing you never know how to use in English; does it go
between two sentences, before a list, between some sentence fragments?
Wait I just used one; was that correct? Oh God.
It’s easier in Java. Your Java “sentences” that do things are called
