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

Example three!
int
z =
28
/ (
3
+
4
);
x is 4.
Why? Even though it’s addition, 
3
and 
4
must be tackled first because
they’re inside parentheses.
 3 +
4
is 
7
. Then we can divide 
28
by 
7
and get 
4
. 
Most math in programming, at least for 90% of developers, is extremely
basic; add two values, multiply two values, etc. So don’t expect to have to
worry about this “order of operations” very often.
Modulo
Also… I debated not mentioning it, but fine, there’s another one. It’s called
the modulo operator and it’s stupid. It uses a percentage sign (because fuck
you that’s why).

---

int
remainder =
5
%
2
;
remainder
is set to 1. Why? Because a modulo performs division, then
gives you the remainder of that division operation.
The only scenario I’ve really seen for this is to check if a number is
even/odd. For example, if a number “modulo 2” is equal to 
0
, that means
it’s even. Because it evenly divides by 2 without a remainder.
boolean
isEven = myNumber %
2
==
0
;
That’s all I’m going to say about it.
Your examples suck
Well, Java would not actually be used for the silly examples above, OK?
Yeesh. Just introducing some stuff.
See the numbers 5, 3, and 7 in the first example?
int
x = 
5
+ 
3
- 
7
;
Because they’re directly written into our source code, those numbers are
hard-coded .
I mentioned this earlier, but no one would ever write Java code like this. If
they want 
x
to be 1, they’ll set it equal to 1 to begin with.
We use these math operators (+ - / *) to calculate things we don’t know the
value of right now, but we will when our program is running!
Maybe you’re making a shopping cart website. Your program might
multiply (*) the current price of a product by the quantity the user selects to
get the total price. Or, your program might decrease (-) the total by one if
the user removes it from their cart.
The logical operators!
These ones are easy peezy.
They’re basically the Java version of these words in English:

---

and (&&)
or (||)
No, that’s not art of a bunch of buttocks. It’s the new operators inside of
parentheses.
Or
Let’s create some booleans ! Remember that data type? A 
boolean
value is
either true or false. This data type goes hand-in-hand with these “logical”
operators.
