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

char
[] userFavoriteLetters =
new char
[
10
];
userFavoriteLetters[
1
] =
'Q'
;
See what I did there? I said “Put the letter Q in the first slot.”
And you can keep doing this shit:
userFavoriteLetters[
2
] =
'C'
;
Hell, you can even jump right to this:
userFavoriteLetters[
7
] =
'Z'
;
Your array, under the hood, looks like this now:
[ , Q, C, , , , , Z, , ]
So we put the user’s favorite letter, Q, in the first slot, then we put….wait.
Hold the phone.
Is that a comma before the Q? Is Q not in the first slot? The first slot
appears to be empty! WHAT’S HAPPENING?!
I’ll tell you: arrays start at 0 in Java . That’s right, slot 0 is the first
position, not slot 1. The correct way to put something in the first slot is:
userFavoriteLetters[
0
] =
'Q'
;
This is
incredibly 
important! Arrays are used all throughout
Java, even if you’re not aware of it at times. And by the way, it’s not just
papa Java coming up with some weird “start at 0” rule, nearly every
programming language does this.

So yes, once your array is created, you can put things into it with some
square brackets 
[]
.
I’ll show a few more examples for your benefit.
String[] words = {
"Hello"
,
"world"
};
This is an array of length 2 because there are 2 things in there.
“
Hello
” is at position 0 and “
world
” is at position 1.
words[
1
] =
"universe"
;
Now, “
Hello
” is at position 0, but “
universe
” is at position 1.
Getting shit from the box
Pretty much the same way you put things in, with some square brackets [].
